This is a little demo file that does something very simple. It takes a value, searches for it in list B, returns the corresponding value in list A. Handy for simple 1 or 2 word lists, where you have the ID list in the same order as the list of actual values. Sometimes you need to hunt 1 list against the other to get an ID or other value.
Just tossing this out there for fun. Maybe it's handy. It's not going to work for every situation but it's lightweight. Enjoy
