New Post: AuthorizeNET Redirect Problem

I am getting another problem in Authorize.Net

we need to add two checkout module on two different page.
the page with blank skin.If we select ONLY Authorize.net,then the PaymentOK.msg" and "PaymentFAIL.msg" templates are working otherwise not.
Means ,If we have two payment method for example. PayPal and Authorize.NET then PaymentOK.msg" and "PaymentFAIL.msg" templates are not working
if we have only Authorize.Net payment method then then templates are working.

how can we solve this issue?

we need paypal and Authorize.Net working simultaneously.
