Flash cs5: Set a variable using a function, then read that variable from a differect function

Question

I have a public variable and I am trying to set it, then read it from a different function:

public var str:String;

public function DailyVerse() 
{
    function create() {
        str = "hello";
    } 

    function take() {
        var message:String = str;
        trace(message);
    } 
    take();
}

My trace results says null. Why does it not give me "hello"?

Thanks ToddBFisher, that worked perfectly! Ascension Systems, yes DailyVerse is a class. — Brandon

I'm not sure why you have this set up this way.... if you want to get and set variable, you use the getter and setter syntax for flash.

private var myRestrictedString:String;

public function get DailyVerse():String {
   if(myRestrictedString == undefined) {
      //Not yet created
      myRestrictedString = "Something";
   }
   return myRestrictedString;
}

public function set DaileyVerse(string:String):void {
   myRestrictedString = string;
}

Now you can access this from outside of your class like so:

myClass.DailyVerse = "Test";
trace(myClass.DailyVerse); //Outputs "Test"

If DailyVerse is supposed to be a class, you use the same principles just place the getter/setter within the class.

Lazy instantiaion rocks! +1UP. I would also suggest adding the underscore _myRestrictedString but that's just my preference.

It is set up this way because I am horrible at programming and Im not sure of what Im doing :) Im attempting to create a website that pulls a daily verse or quote from an XML file, which I have working. I am trying to take those quotes and put them in a variable so I can then send that to a "favorites" database, and maybe let the user email it. I have the variable working, with the quote from the xml, but I cannot trace it from any other functions. Thanks for all the help for both of you. I am going to give this a shot tonight now that I have a better idea of how it should work.
