Paypal Standard Payments 500 ERROR on paypal

[intrafusion]

Upgrading from 1.4 to 1.6.  Running test check outs.

 

I have reconfigured the paypal module and I have paypal payments standard setup  (I had express setup and that works, but disabled it for testing).

 

When a user goes and clicks the paypal image to make that final payment they get directed to 

 

https://www.paypal.com/cgi-bin/webscr

What am I doing wrong?

[intrafusion]

I've reviewed the paypal docs and found the error:

 

https://developer.paypal.com/docs/classic/paypal-payments-standard/integration-guide/cart_upload/#id09BLDK0007Q

 

the busness value is reporting my website address and not the email address for payments:

<input type="hidden" name="business" value="GetTshirty.com">

 

Where does this value get changed at?

 

 

--- updated found that this was the business name field on the module.
