Hi everyone! Merry Christmas to all.

I've been away from LC for a very long time, concentrating on Architecture, but trying to use one of my stacks recently I encountered the "explicit variable" problem and I have forgotten how to resolve it. Here's a snippet of my code:
on mouseup again
if the hilite of btn "L/180" then
    put 180 into myDefl

TIA,
