Thank you for the link and the key. However, searching for the specific key "gv_no=" brought up nothing. I searched for just "gv" and it found several files, including the language file, but not the file that specifies the order of the variables.

My client wants to change the order in which some of the data is displayed (for example the value of the gift certificate).

I'm assuming that must be laid out in a php file somewhere.

Thanks,

John
