Languages in CS cart to pass over to language in bank payment pages

Hi All

I have posted this before, but with no luck. Has anyone managed to create a custom php script, that passes the language a client has selected over to the bank visa payment pages?

I am using English and Spanish languages, and use the ServiRed payment module in CS Cart to carry the order info over. It all works, but I can’t see a code to carry the 001 (English) or 002 (Spanish) over to the bank side.

Is this possible? Has ANYONE ever managed to do this?

Any help greatly appreciated.
