David,

Since wks is defined as a Worksheet type object, you can't get
another sheet reference from it using (). Instead, you should
Set wks to the appropriate sheet and use that unadorned variable
in your VLOOKUP function:

Set wks = Worksheets(choice)
textbox1.text = application.vlookup(CB1.text, _
wks.range("A1:N200"),3,true)

Or, you Worksheets(choice) to specify the sheet:

textbox1.text = application.vlookup(CB1.text, _
Worksheets(choice).range("A1:N200"),3,true)

Hello,

I'm having problem running the following piece of code and
would appreciate any help.

Firstly I've created two comboboxes, the result of one
populates the second. I then want to use the
application.vlookup to populate textboxes on my form.

Private Sub CB2_Change()

Dim appexcel as excel.application
Dim choice as string
Dim wks as worksheet
set choice = CB2.text 'this is the name of the sheet.
Set appexcel = Application

textbox1.text = application.vlookup(CB1.text,
wks(choice).range("A1:N200"),3,true) ' this line errors when I
debug and I think,it is to do with the choice variable.

etc

End sub

Hope this makes sense.

Regards

David
