note 54711 rejected from reserved.variables by nlopess

Note Submitter: buddylee305 at yahoo dot com ---- How would I use this command to pass one variable, say $ticketNum, which is assigned a number of 1335 to it, to the next page accessed after a header refresh? Basically, i calculate a ticketnum, process an email form to send me their trouble and the ticketnumber, then i redirect it to a thank you page after that and i want to pass $ticketNum and tell them what their ticketnumber is. Would I need to use get/post or another variable?
