item number appears to be incorrect is what i am getting over and over again; i am pretty sure the #s are correct.

Hello Gerald,
Thank you for your question about the "Incorrect Item Number" error. Are you entering the item number without additional characters? Sometimes cutting-and-pasting results in extra characters such as spaces (although our software should remove them).
Please let us know if this did not resolve your issue to your satisfaction, and we can take the next step. We are happy to help.
