Moneris Payment Mod - Got it working Sort of BLANK page when processing payment

Has anyone used the Moneris Payment Module

http://www.zen-cart.com/downloads.php?do=file&id=453

any feed back?

I have added this to my site..

And i got some sandbox testing from Moneris -

But once I click on the Confirm Order it brings me to the acttual https://esqa.moneris.com/mpg/index.php page..

Not sure why??

Ok after dealing with this Mod for a bit now..

1. I redid all my code again from the Help notes now it seems to be working
2. When I click submit for the order this is what it does.
- it jumps to there website with a blank page
- then about 10 secs later it comes back to my site saying it was approved or denied
-ODD
3. But it works i'm getting transactions now working..

I'm not sure if this BLANK page will mess of the clients - as there is no text saying "please hold processing CC"

Just wondering if anyone has this working with v1.5.4?

Thanks in advance for any help!

Any updates on this issue?
