Error received when accepting payment through authorize.net

[bbsemail]

I set up oscommerce but have one question and one huge problem:

Problem
When a user clicks checkout and gets to the checkout_confirmation.php file the following error is thrown when Confirm Order is clicked:

The referrer, relay response or receipt link URL is invalid

What do I have set up incorrectly? It must be related to my configuration/misconfig of the payment module, but I don't see how to fix it. I set up processing to go through authorize.net. This is prohibiting me from launching the store for this charity, so any help would be greatly appreciated. I did not configure authorize.net to use relay response.

Question
I configured sales tax for California and oscommerce displays sales tax in the checkout_confirmation.php screen, but there is no title, just a : followed by the tax amount. The variable, heading_tax appears to hold this text, how do I set it? In the Languages/English folder, this variable appears to be set to Tax in the checkout_confirmation.php file.

Again, thank you

bbsemail,
Did you eventually figure out this problem? I am having the same issue right now. I'm pretty sure that the Referrer, Relay Response, Receipt Link must be set in your Authorize.net account:

Note: This information is current as of Nov 30th, 2003
>> login to Authorize.net account
>> click "Settings" link on the left
>> Under "Transaction Response", click "Response/Receipt URLs"

This is the point I'm stuck at. No one mentions what urls to place in the slots (maybe I'm blind).
Default Receipt URL
Default Relay Response URL

Anyone know what pages of the Oscommerce cart are placed here?

Whoops! Sorry for the tiny type. It says "Note: This information is current as of Nov 30th, 2003"

This comment was made by thaymaker somewhere else in response to this problem, and it looks like it is the link you are interested in. I'm having the same problem, but it looks like I might be able to figure it out with the comment already made.

I'm sure you must have resolved this problem by now but wanted to share what I learned with the same problem.

I traced the Response/Receipt URLs link being submitted by oscommerce to be https://my.web.url/catalog_dir/checkout_process.php
