Match Formula to Check if Cell Value is Within a Numeric Range Table

OK, I am trying to create a formula to check what quantity break a cell value falls in. I originally tried using the Min and Max function to match the Low and High value of the break, but I could not get it to work. Now I am using the index and match function. For some reason the match function is returning the wrong row. I want it to return the row that the quantity is less than the high value. For some reason my results are not consistent. What am I doing wrong. File attached. Thanks for your help, feel like I was SO close on this one.
