[ic] Help w/Inventory Pricing Grid

[Jack Sasportas]

Hi everyone, 

I am trying to figure out how to accomplish a pricing grid for an item. 
As an example lets say I sell you a hurricane shutter, you select the
model you
want, then I need to know the height and the width in order to provide
the proper
pricing. 

Lets say you pick shutter1, then we get the height (2.5 feet) , and
width ( 3.2 feet )
the charge would be $3 based on the pricing grid below. 

Height       1     2-3  3-4  4-5 
Width        2-3    $2   $3   $4 
             3-4    $3   $4   $5 
             4-5    $4   $5   $6 

How can I accomplish this via interchange ? 
I tried playing around with some of the inventory tools from admin, but
wasn't
successful... 

Any help is appreciated!
