I have recently set up Paypal Express but want to change to Standard as I don't want the Paypal button on the checkout before the client has a chance to select shipping etc and from what I can see the Standard version is more user friendly.

I have a Paypal Business account and API Username Password and Signature code

So do I just need to install the Paypal Standard Module in Zen switch the API info and then uninstall the Express Module, or is there more to it?

Thanks

David
