check for Null entries in form

[tekila]

I want to check for any null entry (in comboboxes and textboxes) in a form upon clicking "New Record" control and this was what I did to test out one combo:

Private Sub new_record_Click(Cancel As Integer)

If IsNull([Combo]) Then
MsgBox "You must enter a value."
Cancel = True
End If

On Error GoTo Err_new_record_Click

DoCmd.GoToRecord , , acNewRec

Exit_new_record_Click:
Exit Sub

Err_new_record_Click:
MsgBox Err.Description
Resume Exit_new_record_Click

End Sub

Then I received a error message that says "Event procedure declaration does not match description of event having the same name." What's that and how do I solve the problem?

My first guess would be that you should replace

Cancel = True

with

Exit Sub

Give that a shot.
