I found the error. I was using "" around the "+" where I should have been
using '', like '+'.
SELECT
IFNULL(IF(CMBYR=CMEYR,CMBYR,IF(CMEYR="+",CONCAT(CMBYR,CMEYR),CONCAT(CMBYR,'
- ',CMEYR))),' - ')
FROM
TABLE;
Thanks for your help.

Yes it is possible, I was nesting if inside another if w/o any problems,
there is probably something wrong with your syntax . Post the full query
maybe then I'll be able to help you.
