Yeah, I've bumped against that.  I haven't had the same issues with

  REM [expression - something]

so, where I can, I try to calculate the last date and then assign
events backwards relative to them and it has worked out great.  But
going forward causes grief as seen here. :-)

Ah, the SCANFROM needs to go on the last event that would trigger
it.  That's what I was missing.  Testing my various cases, this
works great.  Thanks!
