TOPIC: Need help with DTDonate

I have put in support tickets but thought maybe some users could help. I desperately need help with this! Everything appears to be ok on my site except I keep getting the error message that says: Please notify the site administrator and provide the text that is displayed below: Reason :Transactions of this market type cannot be processed on this system.

My client is having a fit that it isn't working (of course). This is while trying to test with 2 Visa cards that work perfectly everywhere else.

I did a donation transaction at authorize.net in virtual terminal and it went through perfectly. That error message is from the website at http://www.vmmky.org/index.php?option=c ... &Itemid=65

Anyone have any ideas?

Thanks,
Rhonda Bartlett
