Forgot to add that I wasn't sure if there was some sort of "security" concern or other tidbit that I wasn't aware of. I've got a post prepared at least to address that issue which may help others like the tidbits that I found in this forum to address errors encountered.

FWIW, generally speaking with addressing the few issues encountered, this code does/can be used with Stock By Attributes (specifically when using multiple attributes and dynamic dropdowns as implemented in the github version). I haven't worked through the initial display of a 0 price instead of starting at, but I think while reviewing the thread that it is addressed.
