Hello,

I have a customer who sells items which go around doors (aka gasket). I'm facing two issues:

1) How can I change from per item to per foot ?

2)How can I calculate the new unit (per foot) base on door size (e.g.  25 2/3 x 56 7/8) ?

Of course, I will have customer to enter the door size in custom text (attribute) but where and how can I have noC to multiply foot by door size?

Your help will be appreciated greatly.

Thanks.
