Email loop results in function

[blogit]

Hello, i'm working with a shopping cart script that saves user carts to their profile, however it deletes them if they remove items. I'd like to get an email each time they add an item or the function below is ran so i can try and save abandoned carts by emailing the users. The script has no option to save them in the admin back end. I've tried adding a simple mail function with some variables but have only been able to get the userid and some other data to be sent. While messing around with another function in the cart which add's the product to the cart i tried the same basic mail function and the variable i was adding to the email came up as 'Array' in the emails i received. If anyone can show me how to capture the looped information into a variable that i can email my self i would really appreciate it

 

Thanks in advance
