RANK Function error - "RANK has no valid input data"

I am on the verge of tearing all of my hair out, please help!

Here is what I need: In cell M2, I need it to tell me the rank of cell L2 in comparison to cells L10 and L18.
Here is what I use: =RANK(L2,$L$10,$L$18)
Here is what I get: N/A - "RANK has no valid input data"

The closest I can get to isolating the problem is the fact that the values in L2, L10, and L18 all have two decimal places - the function seems to work for cells whose value has no decimal places... how do I get it to accept and calculate for the two decimal place values?

Yes, I have formatted all cells to be numbers, not text.

TIA!
