Cancel = True "variable not defined"

[0 1]

I have this code behind a label called "Cancel":

Private Sub lblCancel_Click()
If Me.Dirty = True Then
If MsgBox("This will undo all of the changes you made to this
record. " & _
Chr(13) & Chr(13) & "Continue?", vbYesNo + vbQuestion, "Undo
Changes") = vbNo Then
Cancel = True
Else
Me.Undo
End If
End If
End Sub

It works fine. But I'd like to reuse this for several forms, so I
tried to move it to a Global Module and call it from each form with
"CancelEventRecord." As in:

Public Sub CancelEventRecord()

Dim MyForm As Form
Set MyForm = Screen.ActiveForm

If MyForm.Dirty = True Then
If MsgBox("This will undo all of the changes you made to this
record. " & _
Chr(13) & Chr(13) & "Continue?", vbYesNo + vbQuestion, "Undo
Changes") = vbNo Then
Cancel = True
Else
MyForm.Undo
End If
End If

But this gives me a "variable not defined error," and highlights the
Cancel = True line. Any suggestions?

Thank you.

Well, you don't have a Dim statement for Cancel, nor is it an argument to the
function. The message is exactly correct - there is no definition for Cancel.
The label's Click event would have the same problem, unless there is a bound
control on the form (very badly) named Cancel.

Since you're explicitly doing an Undo on the form object. there really is no
need for a variable named Cancel, I think you could just omit the line
Cancel=True. It may have made sense in a context of a form's BeforeUpdate
event (which DOES have a Cancel argument) but it's not needed here; if the
user doesn't accept the Continue offer, just do nothing and exit the function.

Note also that you can make this a Function instead of a Sub, and put

=CancelEventRecord()

in place of [Event Procedure] in the label's Click event, or any other
appropriate Event property box.

Got it. That did it. And thanks for the tip about making it a
function.

If the user finds out that escape will do what you are trying to do in code
it can be applied universally and saves a lot of time coding.

Same for deleting a record, adding a new one and record navagation. About
the only button I do use is a close button
