I hope this question comes through a little clearer than my last attempt. I
will reference the actual sheet and cell numbers so I can see what the actual
formula will look like.

I am working on a sheet called xxx-xxxx, I am trying to input a formula in
M2 to evaluate K2. K2 is numeric entry such as 123.12 (3-4 digits before
decimal and 2 digits to the right). I would like the formula to search
column B on
sheet1(there are up to 5 decimals and no whole numbers in each instance) -
once a cell in column b has been identified (i.e. K2 is B5 and less than B6
so I want to identify B5) I want to return the value adjacent to B5 (the one
in A5) back to xxx-xxxx M2.
