Handlers and Scope

[Adam]

Hi all:

Being a Revolution newbie and I all, I really appreciate this list and 
everyone on it.  I'd like to thank Trevor DeVore for responding to my 
first post.  Trevor you've made it look easy, thanks. ;)

I have put to work Trevor's suggestions in a function.  That function 
resides in the script of the first card on my stack.

I am then trying to call that function from the script of a button on 
the card in the following way:

on mouseUp
   put field "fldItemsToFind" into lItemsToFind
   put field "fldNumItemsAllowed" into lNumItemsAllowed
   fMyFunction(lItemsToFind,lNumItemsAllowed)
end mouseUp

When put it into browse mode and click the button, I get Rev telling me 
it can't find the handler fMyFunction.

What is the scope of handlers in relation to the stack, cards in the 
stack, and the elements of each card?

It's probably a very simple fix, but really appreciate the help. ;)

Thanks very kindly in advance.

Adam
