Activating a Function in a Different Stack

You have to be careful about using "this" as as in "this stack",  
"this card", etc.

There are a number of ways around it:

1.  Do this:

function CalledFromDiffStack

-- This refers to the stack etc. that called this one

put CalledFromThisStack into myValue
end CalledFromDiffStack

function CalledFromThisStack

-- this refers to the stack that called this function - e.g. the  
right one!

end CalledFromThisStack

2.  Use "me" instead of "this stack" etc. as in set the xxx of me to  

Also it's better to use the long name of this stack when calling the  
function in a different stack, don't know why, but the short name  
sometimes doesn't work.

Hope this Helps
