Not sure of exactly what you're trying to do or how you're test your variable in message window, but what I usually do is simply use a 'put' statement to check the state of variables.

 

example:

 

on whateverYourFunction

set vola1 = 0.0

do myfunction

put vola1

end whateverYour Function

 

Then check your message window.  This is usually a better way of checking the state of your variables. 

 

If you are passing vola1 as a parameter (hence the subject name), you don't have to declare it global.

 

Hope it helps.  Good luck.
