Hi. Thanks for the reply:
If you are refering to the "if" in the code block you posted then it is there to check that the variable has been set.
Yes. I understand that. What I don’t understand is what should happen if the "if" returns true.
In other words..
If the session variable does not exist…
what should I do?
