For users to log onto a site, I've been using:
IF IsNull(Session("username")) OR IsEmpty(Session("username")) THEN
to see if the var exists. Everything has gone fine, until I've split the code up into a couple of include files, so the IF statement is now in a procedure (I'm using the framework idea of CoverYourASP.com)
But it now says Error: Expected ';' and points to the beginning of IsNull.
Is there a different syntax when I want to use an IF within a procedure block? Cause I can't find anything to tell me where I'm going wrong.
