RE: User Discount Problems

I an interested in this also. As I suspected, you will need to get deeper
into how Minivend (as Mike says "magically") calculates the discount,
subtotal, and total on both the basket and checkout.

For all you know, Minivend may be copying the value in the return as a
string (e.g. return($s * 0.9); to '$s * 0.9') and then recalculating it on
the checkout page - in your case '$s * $myper{""}' would evaluate to
nothing. I'm not saying it is actually doing this, just that it could be
doing somthing other that what you think it is doing.
