How to pass a message to a substack (or back)?

this is a list on some card, a variable or custom property?

Try this in your script in your mainstack:

...
ask "Enter new list item:" with "New list item :-)"
## or whatever you want to ask the user...
if it <> empty then
   if fld "list field" of cd x <> empty then
       put CR & it after fld x of cd y
   else
      put it into fld x of cd y
   end if
...

or something like this, if i understood you correctly ;-)

You can also put this into a handler in your mainstack:

on append2mylist what
    if fld "list field" of cd x <> empty then
       put CR & it after fld x of cd y
     ##append 2 field
   else
      put it into fld x of cd y
     ##fill field
   end if
end append2mylist

...and call it from any other (sub)stack:

...
ask ...
## or not ask...
if it <> empty then
   send "append2mylist" && it to stack "mainstack goes here..."
end if
...
