simple local variable question

[Christopher Mitchell]

Howdy,

I'm declaring some local variables at the top of a card script that I 
need to use in several handlers... here is a simplified recipe question 
that will help me understand why I'm not able to access the values I'm 
assigning to them:

--card script begins here

local rotAngle
put 20 into rotAngle

on mouseUp
    answer rotAngle
end mouseUp

--

My question is, why does this not put up an answer dialog with "20" in 
it? the dialog that comes up is empty.

Thanks,
Chris
