I can not get passed the cofirm page when performing a test transaction

Hello,
I linked my payment gateway api id and transaction key into my ecart 5 shopping cart. I linked every thing in fine and my shopping cart created all the check out forms. Every time I do a test transaction, i can not get passed the confirmation page. I get the error message

"You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'For Flushing Systems,'San-T-Bottle With Twelve San-T-Tabs ',79.95,1)' at line 1."

I get this every time i click on the confirm button on the confirm page. The successful transaction page never comes up. I have tried to look up my error online and many other people have had this error but I still do not know how to fix it. I linked to my payment gateway successfully because every time i do i test transaction i get an email from authorize net with all of the order information, i just cant seem to get passed the error page. I would really appreciate some assistance.
Thanks,
Nate Swan
