[Remind-Fans] Issue with SCHED function

[l0f4r0 at tuta.io]

Hello,

I'm using remind 04.00.00.

My following SCHED function doesn't seem to work:

     FSET sched_func(x) choose(x, -10, 1, 0)
     REM 05 August 2022 AT 09:20 SCHED sched_func MSG %"Test alert%" %1%

Indeed, I get no warning at all (09h10, 09h11 nor 09h20).
NB: warnings for my other timed reminders (without SCHED option) are working.

Does anyone have an idea of what I'm doing wrong here please?

Thanks in advance :)
