OK, thanks to the help of Rob and others, I have a
"setGlobal" function that works

Here it is:
on setGlobal tname, tvalue
  set the tname of button "Button" of stack
"EZGlobals" to tvalue
end setGlobal

- When I hit a button on the calling stack, it creates
custom properties just fine in the button on my
library stack.

But when I ty to poll the values of these custom
properties (which I can see in the inspector), they
are empty but I get no error.

Here's the retrieving function in the library stack

function getGlobal tname
  return the customProperties[tname] of button
"Button" of stack "EZGlobals"
end getGlobal


So for example, I set a global called "myVar" to 144.
I can see it in the custom properties of the button on
my library stack. When I do "answer
getGlobal("myVar")" either from the calling stack or
the message box, it works without an error but I get
an empty value.

Any ideas?

Best
