Ooops, I got the wrong idea from your use of value(merge... etc

You can use the 'send' or 'call' commands to use a function outside the
message hierarchy, even in another stack.

As Andre has shown

send "calc VarA, VarB" to btn "source"
put the result into localResult

where...
on calc VarA, VarB
...do work here
return theVal
end calc

or

insert the script of btn "source" into back
--now the handler(s) are in the message hierarchy
 put calc(varA,varB) into localResult
remove the script of btn "source" from back --now or later
