It should be simple, but it's not working. It seems like the same question as Google Spreadsheet, Count IF contains a string but it still doesn't work. And the semicolon mentioned in the responses of that question just gets eaten, so I'm guessing that's an old format.
Basically I have a column of years (it's not designated as a date column) and I want to return total decade counts. I put:
=COUNTIF(A1:A100, "200?")
I thought that would return a count value for everything from 2000-2009, but it just returns zero. If I remove the wildcard and make it one specific year, I do get a count for that year, so it's the wildcard that's the problem. I've tried "?" and "*" and neither work. What am I doing wrong here? Everything I've read says, including the Google COUNTIF documentation says this should work.
