Found the problem. Aside from the integer problem, the email address was set to Numeric in the Order summary instead of to text... SO, I got through that error, but now I'm seeing this one:
Unknown column 'test' in 'where clause'
Test was the text I put in the item name and the description fields for the 1 cent item. It test a reserved word or why is it creating this error?
THE UNKNOWN COLUMN IS THE ItemName column which is the NAME column in the eCart and it appears to be an error in the OrderDetails DB since it is not added to the OrderSummary, AFAIK...
