Before I buy your pro version I thought I would ask if your plugin could do the following (in a nutshell changes the price per metre depending on the following):

1. A customer would choose a species of wood (first price variable).
2. Then there a 8 table groupings of thickness 6 to 11mm, 12 to 15mm to 19mm etc etc with different prices for the next stage of width.
3. In each of these tables there are width ranges that again change the price of the per metre length.
Hopefully the image will give the best guidance.
