[Remind-Fans] Trigger and shell script issue

[@@]

Hi,

I have a Shell command (hdateN) whose result is a Gregorian date as 2006/1/31:

SET muh shell("hdateN -h 1 1 1427")
 
The MSG command displays the awaited result well:

REM MSG [muh] 

But, REM command combined with TRIGGER does not sisplay anything: 

REM [TRIGGER([muh])] MSG myDate

Would I have forgotten something?

Thanks
