Response Code 99 Error

[jhanson]

I have used the Response Code 99 Tool and have also used the https://developer.authorize.net/tools/paramdump/index.php page to verify my post and other data, but I still get a Response Code 99 error.  

I'm using asp.net MVC3, and here is an example of the form that sends the post:

Sorry for the image.  TinyMCE doesnt like the html it created.

I have tried posting to "https://test.authorize.net/gateway/transact.dll", but the account I am testing is not a Test account.   Any advice?

 EDIT: Forgot to mention I'm doing SIM.

amount need 2 decimal for the x_fp_hash. so on your example need to be 75.00

If you still getting Error 99 that use the https://developer.authorize.net/tools/responsecode99/ to make sure the timestamp is correct.

Thank you for your reply!  I found the problem, but it wasn't necessarily with the 75 or 75.00.  If you take a closer look, you may notice that I have a typo in "x_amount".  Just goes to show how looking at the same problem all day can distract you from checking the simpler things. 

Thank you again for your help.  Unknowingly, you pointed me in the right direction.
