I have a small form that is based off a query. I want a button to become visible or invisible if a textbox is blank or not blank. The form is based off a query and the one textbox is the data field on the form. I have tried a if then statement referring to the box as "null" and "", but either don't work when the textbox is actually empty. Is there a command or something that I can refer to as "no data" ? Or is there another solution. I've even tried the isnull([textbox]) but it doesn't work either.
