HadData, or #ERROR when empty subform

PHP @ December 30, 1969   Views:0

I have two questions:
1) Does anyone have any good examples or descriptions (BETTER THAN THE ONE ON HELP) of the hasdata function. It doesn't answer any of my questions, like does it have to be on a subreport or can it be on a subform,
ex--> me!subreport.hasdata ????

2)#ERROR, when you reference an empty subform you get this in any text box referencing that subform, the above question is in hopes of trapping this error and swapping a few .visable's around.

ANY HELP would be greatly appreciated, especially for the hasdata b/c the only reference to this function is strickly the help file found in access or a reference to it.
