I have upgraded a database fron Access 2 to Access 97. There is no problem when using the old database, but on the 97 version I get type mismatch when I try to open a form

This is the code to opent he form:

Private Sub Form_Open(Cancel As Integer)

Dim dummy, Vertaling As String

Open path & "\" & cg_batchconfiguratie For Input As #1 'Open to read file.

I would be very greatful for any suggestions
