[Remind-Fans] Reminder at 2weeks, 1week, 1day, today

[IanB]

I'd like to set a reminder that triggers:
- 14 days back
- 7 days back
- 1 day back
- on the day

I tried the following to get 14,7,0 days but get a 'type mismatch' error 
which I'm not too sure about:

REM 5 Mar +14 SATISFY [(TRIGDATE() - DATEPART( CURRENT() )) % 7] 
MSG Event is %b


Any suggestions appreciated.

Ian.
