Alex, I followed your instructions and while it took some time to finetune it,
it now works perfectly on my webshop.
Little background:
I'm a musician and sell my official CDs through my oscommerce webshop and do
this by the usual shipping and paypal ipn modules. Works great.
One of my CDs is sold out and I have put it up for download with the aid
of Downloads Controller 5.3 and osC Paypal IPN and this is also working great.
Now comes the challenge (it may be easy for some, not for me):
If I want the customer to have the choice to buy the CD or to download I know
I must do this with the product attributes (as done with instant download) but
how will this work with CD (has weight with shipping/paypal) and download (has no weight, no shipping/paypal)?
I guess I have to make 2 Option Values, but I don't know how the downloads controller
will now if it's a CD or a download.
I hope I make myself clear and that this is the right thread for this.
