If you always want the date a certain number back, I think you can
just assign a variable:
Daysback = ref(O, -7);
etc.
But if that's a fixed date, then I think you have to get the value
when datenum() == (the date you want), or something along those lines.
There is a way to do it, but this is one of the areas I'm stuck on
also. Sorry.
