Another Problem- Please Help

Hi All Again
Thanks so much for the fast response to my other question.
I have now split my serial validation box into 4 separate boxes.
I need to form each of those box variables back into one. I tried using this:
local strSerial = SessionVar.Get("%Ser1%") and SessionVar.Get("%Ser2%")...
but it only used the first variable ("%Ser1%").
What would I use (instead of and or +) to append variables(strings) into one variable(large string).
This should be simple enough to get around.

To concatenate strings, the operator is .. . You could check the help file, as the documentation provided with the product is excellent.
fullstring = string1 .. string2 .. string3;
