Authorize.net - simple checkout-the item you requested is no longer available

[an1ndyaweb]

I have created a website with simple checkout option, where I am offering 7 differnet services with 7 different prices. Now when I have integrated the Simple checkout button, only first two services working fine, not the other 5.

and everytime i am getting an error "the item you requested is no longer available". 

any help is appreciable!

I am using/testing the gateway in Test Mode.

I did copied the link value from Authorize.net button value. But still it doesnot work.

try creating a new one.

Did that too, but suddenly from today its not working. the test a/c was working till day before yesterday. I don't know whether I am doing wrong or Authorize.net don't allow more than 7 services options. But I have seen it's mentioned it can handle upto 100 items.

Thanks
