>If I want to remove a report's field object, if it is blank, how do I do this when the object is in the Page Footer area of the report? There is no option to remove the object

I mean that there is no check box for "Remove Line if Blank"

.

One way to acomplish that, would be to upgrade to VFP8, where "Remove Line if Blank" works in a Page footer. Any other solution would depends on what are you trying to acomplish.
