It looks like I forgot to unlock the cells in the tools and such section, among a few others. Although you could change the price and some of the descriptions, you could not specify any quantity. So it is corrected.
There are a few extra lines where you can add items you might want and I did not think of.
The "pick list" feature for aspects with several options is slowly approaching release. I am shooting for allowing you to add options, but not remove the ones I place. This will allow you, the user, to further customize without the need for unlocking the sensitive formulae.
Thanks for all the feedback.
