I have been having troubles with this but I found out a solution to this. The problem is to declare variables inside a function and retrieve its value from another function--but that doesn't work.

Here is an example of the wrong thing to do:

CODE

function firstFunc () {
     var aVariable = oneValue;
}

function getVariable () {
     trace (aVariable);
}


The trace would return (undefined) because it is undefined in that exact function.

Solution:
do not declare variables inside a function. If you have to, use _root.variableName instead of var variable Name

Here's a sample code:

CODE

function firstFunc () {
     _root.aVariable = oneValue;
}

function getVariable() {
     trace(_root.aVariable);
}


So, tell me what you think. And if there's a better alternative please do post it.
