In the VBA Editor, go to the Tools menu, choose Options, then the General
tab. There, select the "Break In Class Module" option in the "Error
Trapping" frame. Now run your code. It will break on the actual line of code
that is causing the problem.

For some reason my program isn't working. In the excel sheet, I have a
user
click on a button to open a userform.

Now when that button is clicked, a user gets

Runtime error '13'
Type Mismatch

I click on Debug and it goes to

Sub Show()
UserForm1.Show
End Sub

I have no idea why its doing this all of a sudden. Does anyone else?
