Set zero values for results in Access 2003 Reports

[Guest]

I have a report where I calculate days overdue. Problem is if the item isn't
overdue the value is negative. I did a conditional formatting so the
negative values don't show, however when I go to calculate the average days
overdue I get a negative overall value because even though masked the
negative values are there. I need to know where and how to program an Iff
statement in Access 2003 that will take any negative values and set them to
zero. (BTW I know how to do this in Crystal Reports, but apparently Access
doesn't like the way Crystal formats things).

You can use an expression like:

=IIf([DueDate]>Date(), Null, Date() - [DueDate])

Your average of all records overdue should then be:
=Avg(IIf([DueDate]>Date(), Null, Date() - [DueDate]))

The average will ignore records not overdue. Is this what you want or do you
want to figure all records?

Thank you Duane, what you proposed is I think what will work. I wanted all
negative values zero'd out because they are not past due. I have to make
sure that the Null would work for what my supervisor wants, if so then you
have made my day and Thank you again.
