Formula to return headers for 3 highest values in a row into the same cell

I have been at this for a little while now because I really wanted to figure it out on my own but after using match, max, and large the closest I got is the highest value and then another value duplicated which I don't understand how it picked it. I am trying to do a formula that will list the 3 highest values in column U for each set (row) listed by the header in row 34. Cell U36 is a proper example.

The example is a copy of the sheet where the info is. All the dollar values are actually formulas in the original sheet if that makes a difference.

Use this in U35:

=INDEX($L$34:$T$34,MATCH(MAX(L35:T35),L35:T35,0))&","&INDEX($L$34:$T$34,MATCH(LARGE(L35:T35,2),L35:T35,0))&","&INDEX($L$34:$T$34,MATCH(LARGE(L35:T35,3),L35:T35,0))

then copy down.

Hope this helps.

Thank you both of you. Another example of more than one way to solve the problem with excel(that I kept missing lol). There is 1 other thing though. In my example workbook, Q35 and T35 have the same value. If I change R35 to 0, then Q35 and T35 would be tied for 2nd highest and O35,Q35, and T35 would be the 3 highest values but both formulas return the headers of CI,WG,WG (O35,Q35,Q35) instead of the 3 highest. Can either formula be corrected to account for this?
