	I have a Boolean that I need to check for nulls or false values. If I try to look for a null, it gives me an error. What formula can I use to check for a null Boolean?

	Bwsander, I had tried that, but I think the problem occurred when I tried to make the false value appear as text instead of just a boolean answer. This is what I ended up with that worked. If (IsNull({table.field}) OR RTRIM(CStr({table.field}))='') then False else {table.field}
