Syntax Error in Formula

Question: Hi!
the problem come to use this sentence in a Formula for Update Rules:

DATE_FISCYEAR( CRM_EXPEND , FISCVARNT)
CRM_EXPEND --> it's in format YYYYMMDD
FISCVARNT --> contains 'FY'

I tried to insert it into an "IF" like this:

IF ( ID <> '', DATE_FISCYEAR( CRM_EXPEND , FISCVARNT), '')

ID --> Always contais anything

It doesn't give Syntax Error, but when i start the load, it fails.
