Here is the current formula.
=IFERROR(YEAR([Close Date]@row) + "-" + MONTH([Close Date]@row), " ").
The results of this formula are causing sorting errors. I would like the result when the the month is less than 10 to appear with 2 digits. For example, the current result for September 2022 is 2022-9. I would like it to appear as 2022-09. I tried adding an IF statement on the MONTH, but could not get it to work.
