 So one of the things that we can do with our criteria is instead of it just being explicitly say for example a A word like red hot chili peppers. We can actually assign it Sort of a greater than or less than value say for example. We come back to track Well, if I go to unit price for example, maybe I want to see what is the most expensive. I'd Track I happen to have I don't know there might be some that are worth $3 for all I care let's find out so now all of a sudden I've got my name I've got my track, and I've got my unit price and in my case. I'm going to go ahead and sort and Descending order from unit price. I hit run and what I can see is okay the highest We have is $1.99. Well, maybe I don't want $1.99 I want to see anything that may be less than that maybe a little less than $1.00. Well, what I can do is I can come into criteria Criteria and I can actually do that. I can say well, I want to look for any unit price That is less than $1.00 and So all of a sudden guess what I happen to see all of the tracks. They're now under $1.00
