I had somebody implement a script for me, so I'm a little lost on how/where to set the code to give me back a transaction id for tracking or for the customer's to print for their records.
I have a payment processing page that includes the below code. I seeat the top,var $trans_key = ''; and down lower, several options under "// response information". But I'm just not sure how to set these to give me that information to echo/use on the confirmation page.
