How to make excel use a column based on condition in vlookup

I have several columns with different prices for my location codes. I want to use a certain column's price based on the shipping amount. For example, if my amount is less than 100 I would want to use column B's price in the attached spreadsheet. If the amount is greater than 20,000 then I want to use column K. If the amount is 3,500 then I would use column G. How do I do this? I imagine it is some sort of Index Match or a conditional formula in the lookup column of the vlookup. I may have more conditions then the attached example, so I think "IF" is limited to 7 nested formulas so that wouldnt scale. Thanks in advance.

You can use MATCH to get the column_index of a VLOOKUP, e.g. like this

=VLOOKUP("ATLA",A$2:K$300,MATCH(3500,B1:K1)+1,0)

where "ATLA" is the lookup value and 3500 the amount. Obviously you can use cell references for those values e.g. like

=VLOOKUP(M2,A$2:K$300,MATCH(N2,B1:K1)+1,0)

where M2 and N2 contain the lookup values

This is getting close, but if you notice, 3500 is not one of the columns. The columns may or may not have a pattern. I was thinking ROUNDDOWN, but if there is no pattern then I cannot really use a certain place to round down to. I need something like the max column that is still less than the weight that I specify. In your example, I would want it to "think" 3000 is the highest value that is still under 3500 so use that column.

WHOA! You're right! I took off the +1 after your MATCH and it does work! You rock! And thanks for a pretty gosh darn simple solution!
