Parameter error on 2checkout

[alougher]

I get a parameter error message when completing checkout. This didnt happen before. I am running it in test mode. Has anyone else seen this error?

 

Parameter Error.

 

 

Incorrect parameters were supplied therefore this purchase cannot begin.

 

If you are attempting to purchase from a web site please contact the web site so that they can correct the error.

 

If you are designing your web site consult the 2Checkout.com Admin Area for the proper codes.

Finally a response:

 

Please ensure all the correct parameters are making it to our payment page when making the sale. Look at the link and ensure the seller id, amount and order number are present.

 

????

 

I am using the SSL 2checkout module fix which I copy & pasted from another thread which seems to be working fine for others.

 

Anybody got any ideas?? anyone anyone? :)

Al,

 

Make sure that item that you're checking out with does not have a value or price of less than zero. 2CO does not process any order without a dollar amount. Also check your store ID #...it's NOT your user name.

 

Good luck!
