Index Match Formula Error

I have used an index match formula numerous times, and have never had a problem. For some reason it just won't work today. I have the following values in my sheet:

Cal 08 60.00
Cal 09 57.00
Cal 10 61.00
Cal 11 56.00
Cal 12 44.00


Look up value 60.00
Result Cal 08


When 60 is entered, Cal 08 is displayed as it should be.
When 57 is entered, a #N/A error is displayed.
When a number that is not in the list such as 99 is entered, Cal 12 is displayed

I have attached this spreadsheet. Hopefully someone can explain to me why this isn't working.

What is your expected result when 99 is entered?

You need either
=INDEX(A$1:A$5,MATCH($B9,$B$1:$B$5,0))
This makes it an EXACT match, and will work for all entries that exist in A1:A5

Or, leave the formula as is, and sort the data by column B ascending.
This will be a closest match, and will make an entry of say 63, return the same value as if you entered 61.

Thank you both for your help! A second opinion is all I needed to solve that little mistake.
