VBA excel export to access - excel

Question

Hi I am trying to write a macro that takes the user input from an excel form and adds it to a access table. Using the following code:
Dim cnn As ADODB.Connection
Dim rst As ADODB.Recordset
Dim wsh As Excel.Application
Set cnn = "db.accdb.connection"
Set rst = New ADODB.Recordset
rst.Open "table", cnn, adOpenKeyset, adLockOptimistic, adCmdTableDirect
With rst
.AddNew
.Fields("column1").Value = textboxvar
.Update
End With
with textboxvar previously defined. But it wont work and I don't know why.

after searching for a long time. The top voted post in this thread already answers the question:
Using Excel VBA to export data to MS Access table
This just has to be updated to work with Access 2016:
Public Sub UploadExcel()
Set cn = CreateObject("ADODB.Connection")
dbPath = 'type your database path in here
dbWb = Application.ActiveWorkbook.FullName
dbWs = Application.ActiveSheet.Name
scn = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" & dbPath
dsh = "[" & Application.ActiveSheet.Name & "$]"
cn.Open scn
ssql = "INSERT INTO TableName ([Field1], [Field2], [Field3]) "
ssql = ssql & "SELECT * FROM [Excel 8.0;HDR=YES;DATABASE=" & dbWb & "]." & dsh
cn.Execute ssql
End Sub

Example that declares, sets, opens connection:
Dim cn As ADODB.Connection
Dim rs As ADODB.Recordset
Set cn = New ADODB.Connection
Set rs = New ADODB.Recordset
cn.Open "Provider=Microsoft.ACE.OLEDB.12.0; DataSource='C:\path\databasename.accdb'"
rs.Open "SELECT * FROM MyTable", cn, adOpenKeyset, adLockOptimistic
