Paypal and PaypalExpress are two different animals - what you seem to want is 
the standard Paypal. There is a module for this, but it's not mine, I've 
never used it and so I can't speak for it.

However, Paypal/Ebay have an horrendous reputation for jumping on people with 
little or no excuse, and what you are doing here is giving them a very good 
excuse to jump on you. The Express checkout flow is documented as needing to 
flow the way I  built it, ie the customer returns to your site and then makes 
final payment by clicking. This also lets you update shipping and taxes by 
the way.

I suggest you look at using the standard Paypal module.  If you need to handle 
IPNs, I do have a separate PaypalIPN module for that which could do with a 
little more testing ...
