Peter-
Do you want the field to be blank? Or do you want the whole line that the field appears on to be removed from the report? I'm assuming the former. Then did you try simply setting the format of the field to numeric and blank if zero

>I have a report that has a field that is a currency sum printed in a GROUP footer. Based on info in another field, sometimes this field is blank and the customer would prefer it to NOT be there instead of $0.00.
