Authorize.net not working with Powerstore3

The gateway tested fine one week ago, I loaded product and now when I try to purchase anything it refuses credit cards and says either credit card info or billing address is wrong,,
the thing is IT WORKED A WEEK AGO..nothing changed but now it doesn't work...I even changed the transaction key from Authorize.net and still nothing..

WHAT CAN I DO? The customer is freaking out....

I just entered a new bogus product and the payment gateway worked...
I tried another product I loaded - doesn't work....
I WENT BACK AND ADDED ANOTHER NEW PRODUCT...DOESN'T WORK AGAIN

WHAT THE HECK IS GOING ON? My customer is angry as hell and I am getting
ticked off and wasting hours of time - could someome please assist me?

index.php

Looks like you found the cause of the problem?

authorize.net can have some pretty strict limitations to the data that is sent, for product info:
Item ID - Up to 31 alphanumeric characters
Item Name - Up to 31 alphanumeric characters
Item Description - Up to 255 alphanumeric characters
Quantity - Up to 2 decimal places, must be a positive number
Item Price - Up to 2 decimal places, must be a positive number

yes Jason...finally. Thanks for the additional info though...I will keep it in mind as I continue.....I begged the customer from the beginning to use PayPal...wish he had!

Thanks again,

Mark
