First: Fix what you're doing with hashes. You need the stock hash to look like:
{name} => [stock, cost]
And your drops (that is, the stuff the customer wants to drop into their cart) should look like:
{name} => [quantity]
I think. I'm not sure how I'd go about matching the quantity to *only* the stock...yes I am! I know! List matchup!
($stock, $cost) = ($stock{name})
In a smallish loop that handles the match! Goodie goodie.
Next, you've got to go through and fix all the old references to param("box$j"). Then clear out $j. The cleaner it is, the easier it is to understand, and the better it will be. (And the easier it will be to maintain, too.)
Next...next what?
Well, by the time I finish that stuff, I'll know exactly what I need to fix next.
