Report Calculation

[Fish521]

I have a report which I have 2 text box fields in the report footer
=sum([MTM]) and =sum([EID OT'd]); and then a calculation between those 2 text boxes =[txtMTM]-[txtOT]
These calculations work fine if there is an option button marked otherwise it brings back no data. How can I get the txt box to populate with a zero whent he field is Null. I have tried a couple of IF expressions but could not get them to work

In an unbound field

=NZ([textMtm],0)-NZ([textOT],0)

The NZ expression allows for any number/text to be substituted for a null

Thanks, looks like the calculation is going through now but is there a way to get rid of the error# in that field so it shows 0.

If you want a summary text box to display 0 when the report doesn't return any records, you need to use something like:
=IIf([HasData],Sum([YourNumericField]),0)
