Excel Commission Formula - excel

Question

Wondering if I could get help getting the correct formula to figure out the comm% based off the price it was sold at.
Basically, there are two spreadsheets.
First one is our price grid to show what the commission pct will be:
Product - 20% - 15% - 10%
Widget 1 - 3990 - 3490 - 3090
Widget 2 - 4990 - 4490 - 4090
Widget 3 - 5990 - 5490 - 5090
The second spreadsheet would list the Products sold and at what price it was sold at:
Widget 2 - $4690
Widget 3 - $5100
Widget 1 - $4000
I was thinking INDEX/MATCH. I can do the MATCH correctly to find the correct row, but I'm not sure how to incorporate that price range lookup into the formula.
In the example I gave above the commission should be 15%, 10% & 20% respectively.
Need to create a formula that matches the Product and then takes the price sold at and matches it to what column it would fall under and give me the % for that column.
I've spent weeks search the net and I can only get half way there. The MATCH to figure out which row the Product is on is simple, it's the price matching that's got me stumped.
Thanks.

You can solve this by making use of the rarely used Hlookup function, using it's range_lookup option. The only requirement for it is that you reorder your commission data from low% to high%. like this:
Product 10% 15% 20%
Widget 1 3090 3490 3990
Widget 2 4090 4490 4990
Widget 3 5090 5490 5990
If you've done this, you can use this formula to get the correct commission
=OFFSET(Sheet1!$A$1;0;MATCH(HLOOKUP(INT(SUBSTITUTE(B1; "$"; ""));INDIRECT("Sheet1!"&MATCH(A1;Sheet1!$A:$A ) & ":" & MATCH(A1;Sheet1!$A:$A ));1; TRUE);INDIRECT("Sheet1!"&MATCH(A1;Sheet1!$A:$A ) & ":" & MATCH(A1;Sheet1!$A:$A)) )-1)
This is the breakdown:
Format input as integer (commission data is int, values are $)
SUBSTITUTE(B1; "$"; "")
Use the input to put together the reference row for the Hlookup. We use indirect to add the sheetname and ":" to the reference.
INDIRECT("Sheet1!"&MATCH(A1;Sheet1!$A:$A ) & ":" & MATCH(A1;Sheet1!$A:$A ))
Use Hlookup to find the matching value:
HLOOKUP(INT(SUBSTITUTE(B1; "$"; ""));INDIRECT("Sheet1!"&MATCH(A1;Sheet1!$A:$A ) & ":" & MATCH(A1;Sheet1!$A:$A ));1; TRUE)
Use the found value in a horizontal match function to find the used column, and substract 1:
MATCH(<hlookup>; INDIRECT("Sheet1!"&MATCH(A1;Sheet1!$A:$A ) & ":" & MATCH(A1;Sheet1!$A:$A))) - 1
Use Offset to find the matching value
Offset(Sheet1!$A$1;0; <match>)
