Re: session var puzzle

Hi, As I have no idea what those var contain .. what does a print_r() of it give you? print it right when you assign it to the session var to check if it actually contains a value. like: print_r($Data['ID']); and maybe even print_r(intval($Data['ID'])); I suspect that this $Data['ID'] is empty from the start - otherwise you ought to have something in your session var.
