Hello,

This is my first time using DateDiff and it looks pretty straightforward; I fear, however, that I keep getting the following error:

Incorrect parameter count in the call to native function 'DATEDIFF'

My goal in the code below is to get all records that are more than 3 days old; the Timestamp variable looks like: 2011-05-22 20:26:42

Code MySQL:
SELECT * FROM `homepage_homeschool_schedule` WHERE DATEDIFF(DD,Timestamp,CURRENT_TIMESTAMP)>3

Any help would be appreciated.
