In the last pair of examples where it fails, you know you are first assigning the value of $Data['ID'] to the $_SESSION['CategoryID'] and the over-writing that value with the value of intval($Data['ID'])? Why are you assigning $Data['ID'] to it if you are going to overwrite it? If those other tests work then I doubt that it is a session problem. I'd double-check to make sure that $Data['ID'] is holding a reasonable value.

I have one page, index.php. when it calls mod_sub, a directory type of page is printed. Here I am trying to set a session var of the most recently selected category to allow the user to return the to same place in the directory. when I do this: $_SESSION['CategoryID'] = 230; in mod_sub then in mod_profile: print($_SESSION['CategoryID']); will print 230 when I do this: $Tmp = 230; $_SESSION['CategoryID'] = $Tmp; in mod_sub in mod_profile: print($_SESSION['CategoryID']); will print 230 BUT, when I do this: $_SESSION['CategoryID'] = $Data['ID']; in mod_sub $_SESSION['CategoryID'] = intval($Data['ID']); in mod_profile: print($_SESSION['CategoryID']); will print '' and 0 I am setting several other session variables throughout the code without any unexpected behavior. I have even tried changing the index to something odd in case I am resetting 'CategoryID' somewhere and forgotten it. But no matter what I try, once I set it "= $Data['ID']" I get the odd result. BTW, if I print $_SESSION['CategoryID'] from mod_sub right after setting, it holds the expected value. This is really frustrating, I must be missing something basic about the way session vars can be set.
