Matching specified range vs entire column

I'm trying to use the match function to identity the row a value is in, however i am running into an issue. Because of the nature of my data, I want to specify the range in which i would like to make the match. This is where I am encountering my issue. If I use the entire column in my match function, I obtain the correct result. However when I try to specify a range that includes the correct value, I get the incorrect value.

L908 = MAX(K120:K360) = 15.01 so I know this value exists in this range

=MATCH(L908,K:K,0) returns 248 (correct) K248 = 15.01

=MATCH(L908,K120:K360,0) returns 129 (incorrect) K129 = 5.3

Is there something I am missing?

Thanks.

The match function returns not the row number, but the row number within your range. So... =MATCH(L908,K120:K360,0) returns 129 (incorrect) K129 = 5.3 returns 129 because the 129th row in 120:360 was matched.
If you consider K120 Row "1" then the 129th row is K248.
