However, if you do this, it will amount to the same thing:
If {MyBooleanValue} then 'X' else ''
However, what type of field is "MyBooleanValue" in the database? If it's really a bit or a number (most types of databases don't have "Boolean" fields), then you'll need to do this:
If {MyBooleanValue} = 1 then 'X' else ''.
Or, if the value is coming from a formula, what is that formula?
