I had a customer attempt to use an e-check this morning. I verified her account number and her routing number both with her, and with her bank.

When she clicked "Next" after having put in the information, the screen blinked, and took her right back to the same screen. All fields were filled in; there were no errrors or anything reported, it just didn't "Go".

Is there some error checking or checksum or length validation or something for E-Check processing? I had to take her order information over the phone to be able to place her order. :(

Negative. Payment Method: "eCheck Checking Account"

Drat.

"Check" doesn't let them put in their account/routing numbers. Now I have to find out if Sage does e-checks, and how that works, and have you build that in.

It's a never ending battle. (Edited: it's not a battle for you.. I didn't mention e-checks when I sponsored SagePay.)

Yes, in the buynow module settings under the payment method setup section check the box titled "Check"
