The problem I have is I'm not a PHP Developer.
I don't even know where to start and what exactly do I have to do.
Is there an Australia Post Server Behaviour?
Do I create it by copying the code inside "//if using UPS" and "// end if Using UPS" and then changing it?
I can see so many different files unique to UPS for example ("WA_eCart/WA_eCart_UPS_PHP.php")
How do I "craft the charge rule"?
