Hello Joel,

Unfortunately I cannot help you with the use of custom code, but if you have any doubts or issues on how to add them in the pages you made with WebSite X5 you can ask me. Generally speaking since the functions do not depend on WebSite X5, you can search useful information about the custom code with search engines like google or wait until someone on the community of Answers can help you.

For the payment code you need to add the variables [PRICE] and [ORDER_NO] in the payment code you got so the program fills them automatically during the purchase procedure. This code needs to be added in step 4 - shopping cart - in order management by adding a new payment type and in the new window choose "type" and then select pay now and from the drop down list choose custom code so you will be able to write the payment code there.

Many thanks!
