Problem with adding columns

[Jake81499]

Hi, I'm completely new to databases and I have a question.

I created an expences database and Everything seemed to be working fine at the start.

The database first three columns are date, item and purchased from. The next 6 databases are card numbers, checks and cash.

The database keeps a running total of each numerical column at the bottom of the list and a grand total to the right of the running total.

It was going fine but I stated getting a '###' in the totals at the bottom.

Any Ideas?

Thanks

Perhaps your display field may not be wide enough.
