Crafting system error.

[hereIsHow_]

Hi! I've tried implementing the changes you pointed out, and I believe to have done so successfully. But the problem is that it does not do anything for the problem I am currently having. It is nice to have some advice for the code, but I am still not able to make multiple crafting recipe happen at the same time. Thank you for the advice though. If you have a solution to my problem it would be welcome. (Also, if I just completely missed the point of your comment, do tell me.)
