Organizing product. I'm trying to create a hierarchy chart I guess you could say. If the product is one category then the next choices will depend on the first choice. I understand how to create a drop down list so for my first group I'm good. But for my next column I want it to be specific to the prior choice. Also I'm using Data from seperate sheets so my final sheet where things are organized is clean. Could I get some assistance I've been searching for days. Thanks!
