Code for a platform moving back and Forth - phaser-framework

Question

I'am trying to make a game where the character can jump on a platform that's moving Horizontally, once the platform reaches a specific point it comes back and it repeats. However I have had some trouble finding the correct way to write the code for this I tried using setVelocityX() is looks like this
var movingPlatform = {
moveRight : function(){
platforms.setVelocityX(100)
},
moveleft : function(){
platforms.setVelocityX(-100);
}
}
var move = true;
if(move = true){
movingPlatform.moveRight()
}
if(move = false){
movingPlatform.moveleft();
}
if(platforms.x <= platformMinX){
move = true;
}
if(platforms.x >= platformMaxX){
move = false;
}
all this did was when the platform reaches the 'platformMaxX' point it just moved back and forth in that area so 'movingPlatform.moveRight()' is still being called

dude.setVelocityX(direction * 100)
}
function flipX ()
{
direction = - direction
