Automation Error

[Susan]

I have a macro running on exit of the question number
field of a field in a form. The condition in the macro
is:

[QuestionNumber] Like "B-501.2"

If this is "True" I'm running the Action "GoToRecord"
Record: GoTo
Offset: 84

All this works fine...BUT...when I Refresh the form and
move to the next Section of Questions (Example Section C)
we get a popup error box that has "frmMainMenu" as the
title in the blue header and the Yellow triangle with an
exclamation point and the words "Automation Error!" and
an "OK" button. When we click OK, it continues to work
correctly and I don't see any errors in data or
anything.

I need HELP to get rid of this Error Message!
Thanks!!
Susan
