Such as, My product has two different wood choices to make i.e. Maple for the body and Zebrawood for the accent then they get to choose size 6epi or 8epi. 
For the main wood choice there are about 10 options and for the accent wood options there are also about 10 and this option is part of the size option. So I may have 2 zebrawood, 10 maple, and 3 cherry in the 6epi size and 12 Purpleheart, 1 maple, 6 cherry, and 3 ash in the 8epi size. How can I set up the product so I can edit the quantities of each drop down box selection (size, and both wood choices). Currently it lumps them all together i.e. Cherry/zebrawood 6epi .... I just want it to give me three sets of choices separately.
TIA,
Janet
