Keep getting error "Conflicting declarations: val open: ImageButton, val open: ImageButton" - android-studio

Question

I'm still in the proccess of creating my app. I'm trying to make it to where when i click the imabe button it will go to a new activity. each image button has it's on activity.
code*
`
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main);
val open: ImageButton = findViewById<ImageButton>(R.id.card1)
open.setOnClickListener(View.OnClickListener {
val intent = Intent(this#MainActivity, TMs::class.java)
startActivity(intent)
})
val open: ImageButton = findViewById<ImageButton>(R.id.card2)
open.setOnClickListener(View.OnClickListener {
val intent = Intent(this#MainActivity, Schematics::class.java)
startActivity(intent)
})
val open: ImageButton = findViewById<ImageButton>(R.id.card3)
open.setOnClickListener(View.OnClickListener {
val intent = Intent(this#MainActivity, PartsCheatSheets::class.java)
startActivity(intent)
})
val open: ImageButton = findViewById<ImageButton>(R.id.card4)
open.setOnClickListener(View.OnClickListener {
val intent = Intent(this#MainActivity, GeneratorLoadWiring::class.java)
startActivity(intent)
})
val open: ImageButton =findViewById<ImageButton>(R.id.card5)
open.setOnClickListener(View.OnClickListener {
val intent = Intent(this#MainActivity, Hdt::class.java)
startActivity(intent)
})
val open: ImageButton =findViewById<ImageButton>(R.id.card6)
open.setOnClickListener(View.OnClickListener {
val intent = Intent(this#MainActivity, GCP::class.java)
startActivity(intent)
})
val open: ImageButton =findViewById<ImageButton>(R.id.card7)
open.setOnClickListener(View.OnClickListener {
val intent = Intent(this#MainActivity, SP::class.java)
startActivity(intent)
})
val open: ImageButton =findViewById<ImageButton>(R.id.card8)
open.setOnClickListener(View.OnClickListener {
val intent = Intent(this#MainActivity, Cummins::class.java)
startActivity(intent)
})
}
}`
when its set up like this it works but only when i click the first one then go to the second one and so on down the list.
code*
`
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main);
val open: ImageButton = findViewById<ImageButton>(R.id.card1)
open.setOnClickListener(View.OnClickListener {
val intent = Intent(this#MainActivity, TMs::class.java)
startActivity(intent)
val open: ImageButton = findViewById<ImageButton>(R.id.card2)
open.setOnClickListener(View.OnClickListener {
val intent = Intent(this#MainActivity, Schematics::class.java)
startActivity(intent)
val open: ImageButton = findViewById<ImageButton>(R.id.card3)
open.setOnClickListener(View.OnClickListener {
val intent = Intent(this#MainActivity, PartsCheatSheets::class.java)
startActivity(intent)
val open: ImageButton = findViewById<ImageButton>(R.id.card4)
open.setOnClickListener(View.OnClickListener {
val intent = Intent(this#MainActivity, GeneratorLoadWiring::class.java)
startActivity(intent)
val open: ImageButton =findViewById<ImageButton>(R.id.card5)
open.setOnClickListener(View.OnClickListener {
val intent = Intent(this#MainActivity,Hdt::class.java)
startActivity(intent)
val open: ImageButton =findViewById<ImageButton>(R.id.card6)
open.setOnClickListener(View.OnClickListener {
val intent = Intent(this#MainActivity,GCP::class.java)
startActivity(intent)
val open: ImageButton =findViewById<ImageButton>(R.id.card7)
open.setOnClickListener(View.OnClickListener {
val intent = Intent(this#MainActivity,SP::class.java)
startActivity(intent)
val open: ImageButton =findViewById<ImageButton>(R.id.card8)
open.setOnClickListener(View.OnClickListener {
val intent = Intent(this#MainActivity,Cummins::class.java)
startActivity(intent)
})
})
})
})
})
})
})
})
}
}`

Answer 1

Change:
val open: ImageButton = findViewById<ImageButton>(R.id.card1)
open.setOnClickListener(View.OnClickListener {
val intent = Intent(this#MainActivity, TMs::class.java)
startActivity(intent)
})
To:
val card1: ImageButton = findViewById<ImageButton>(R.id.card1)
card1.setOnClickListener(View.OnClickListener {
val intent = Intent(this#MainActivity, TMs::class.java)
startActivity(intent)
})
And do like this for the other buttons as well

Answer 2

Do it like
val open1: ImageButton = findViewById<ImageButton>(R.id.card1)
val open2: ImageButton = findViewById<ImageButton>(R.id.card2)
val open3: ImageButton = findViewById<ImageButton>(R.id.card3)
val open4: ImageButton = findViewById<ImageButton>(R.id.card4)
val open5: ImageButton =findViewById<ImageButton>(R.id.card5)
val open6: ImageButton =findViewById<ImageButton>(R.id.card6)
val open7: ImageButton =findViewById<ImageButton>(R.id.card7)
val open8: ImageButton =findViewById<ImageButton>(R.id.card8)
open1.setOnClickListener(View.OnClickListener {
val intent = Intent(this#MainActivity, TMs::class.java)
startActivity(intent)
})
open1.setOnClickListener(View.OnClickListener {
val intent = Intent(this#MainActivity, Schematics::class.java)
startActivity(intent)
})
open2.setOnClickListener(View.OnClickListener {
val intent = Intent(this#MainActivity, PartsCheatSheets::class.java)
startActivity(intent)
})
open3.setOnClickListener(View.OnClickListener {
val intent = Intent(this#MainActivity, GeneratorLoadWiring::class.java)
startActivity(intent)
})
open4.setOnClickListener(View.OnClickListener {
val intent = Intent(this#MainActivity, Hdt::class.java)
startActivity(intent)
})
open5.setOnClickListener(View.OnClickListener {
val intent = Intent(this#MainActivity, GCP::class.java)
startActivity(intent)
})
open6.setOnClickListener(View.OnClickListener {
val intent = Intent(this#MainActivity, SP::class.java)
startActivity(intent)
})
open7.setOnClickListener(View.OnClickListener {
val intent = Intent(this#MainActivity, Cummins::class.java)
startActivity(intent)
})
