Can't provoke a response code of 3 or 4 in sandbox

[keithstacy]

I'm building up a card-not-present payment system for a non-profit organization.  Having followed the instructions I've found, I can submit test transactions that return Accepted and Declined responses.  However, I've not been able to invoke the Error or Held for Review responses. Where should I start looking for the issue?

SIM or AIM?

Here a list of response

http://developer.authorize.net/guides/SIM/wwhelp/wwhimpl/js/html/wwhelp.htm#href=SIM_Trans_response....

for 3 you can do with missing/invalid cc#, invalid expired date, etc

for 4, you can do the Partial Authorization Responses as show in

http://developer.authorize.net/tools/errorgenerationguide/

or setup something on the merchant account settings to flag merchant review

I am using AIM.  

I will give your suggestions a shot.  I'll let you know what I find.

Thus far, my QAs can't provoke an Error, because of the validation code in our front end; it prevents users from submitting invalid CC #s and exp. dates.  So I'm not going to worry about that, unless there's some other way of doing this.  

So regarding Hold for Review: having done an AIM implementation, is there something my QAs can do?  I looked at the docs for AIM, and what I have seen doesn't give me the desired result.

for #4, you can change the Security Settings  on the test merchant account.
