Help needed with formula 2

[JBourne77]

I need help with the following formula. If my field is NULL, I want it to print the word "NULL" else my field value.

IF ISNULL({Data.FSAllowed}) THEN 'NULL' ELSE {Data.FSAllowed}

This is not right obviously, because I am getting an error indicating a String is reqd. Not quite sure how to fix it.
