report running sum

[prgm]

I have a report that isusing a calculated txtbox to hold
a running sum. It worked fine, then it started to display
#Name?. I have no clue how to fix this can anyone please
help?

Paul,
It is possible that one of your referenced fields has been
deleted - the #Name is a reference error. Or it is
possible that the SUM is Null or Zero depeending on the
number format.
HTH.

Make sure the textbox is not named the same as any of the
variables in your table or query.
Have a great day.
