Ray,
Looking further into this, I believe that the odd characters in the eCart1_Items session are at the end of the first item where the second item's id begins.
I'm not sure if the Session_GetContent function in the WA_eCart_Definition_PHP.php file is where this string is created or if it's a different one but I was looking at it to see if I could figure out where my code provides that data. That way I could try and trace down my mistake. Can you tell me which function is responsible for that sessions string?
Thanks
