Excel Help with Upper and Lower Bounds

Hi there, I posted this question a few days ago and got a solution, but I think the solution is work backwards? If that makes sense... I need to return the price tier the item falls into based off current price and two bucked, but looks like its reversing. Does that makes sense? Let me know if it needs more clarification.... Can't figure out where I'm going wrong... Thank you!

Please give an example of what you think is wrong.

For example, the class number on the first tab of 101 and a price of $284.99, according to the matrix on the second tab, an item in class 101 and between 150-500 should fall in the High price tier bucket, but the formula says it's "Low". Does that make sense? Hope that helps! Thank you!!!

Change the formula in C5 to


and copy down.

By the way, I would suggest formatting columns "C" and "D" on the Matrix sheet so that the numbers display two decimal points because as it is it appears that for example 150 is both the upper bound of "medium" and the lower bound of "high", when in fact the upper bound of medium is 149.99.

You need to start the Array range of the INDEX function from 1, or adjust the return from the SUMPRODUCT function according to the INDEX start row. See the below bolded text from each function.




The reason for that is the SUMPRODUCT function is returning the row number of that matching price tier. That row number is used as the index of the item in the specified array within the INDEX function, which if you start at a row other than 1 will be the incorrect index.
