Need some1 with exp with pap4 & interspire shopping cart

I need someone to get this plugin to work with my shopping cart my shopping cart is Interspire..my affiliate program is post affiliate pro. I need to make this plugin work [login to view URL] Now ...i talked to the makers of the affiliate program they need a variable that will pull up the email address of the person after he purchases thus giving the potential affiliate a way to get payed for the lifetime of that person. But the shopping cart doesn't have that variable so i emailed them and this is what they said. the variable goes in here [login to view URL]('varable in here'); were it says Hi henry, Unfortunately we do not have a variable for the email. The only two variables that work for the afilliate settings are the following: %%ORDER_AMOUNT%% %%ORDER_ID%% You would have to modify the PHP code in order to get more variables. This can be done by editing the ThaksForYourOrder() method in the includes/class/[login to view URL] file starting on line 177. My recommendation would be to look for a developer on a site such as [login to view URL] who is familiar with our shopping cart platofmr and can make this kind of modification for you. Let me know if you need further clarification. Best Regards, Emilian Felecan Software Engineer, Support [login to view URL] So this is what i need someone to do. If you understand this than great lets egt it done...so this should be a simple job for osmeone that knows what they are doing...a couple edits of the php code and its all done
