[RESOLVED] trouble calling function

[sea ryder]

Hello,

I am using Flash CS3 with actionScript 2.

I have created a funtion that works fine, but I've decided to call it from a different location and it is not working.

Here is the code I am using:

//create a string
var hiliname:String = new String("");
//give the string a value
hiliname = "ib1";
//trace the string - this works 
trace(hiliname);

//find out if there is an a or b or c in the string 
if (hiliname.substr(1,1) == "a") {
    trace ("found an a");
    expand1();
        
} else if (hiliname.substr(1,1) == "b") {
//trace to show the string found a 'b' - this works
    trace ("found a b");
//call the funtion - here is where the problem lies
    expand2();
        
} else if (hiliname.substr(1,1) == "c") {
    trace ("found a c");
    expand3();
}

expand2 = function () {
//trace to show the function is called
    trace ("called expand2");
} 

this is what traces:

ib1
found a b 

I also call the expand2 function from a button, and that works (traces "called expand 2") but it doesn't work with the above if statement. I am confused by this because the trace in the if statement works.

All of my code is in the same location, at the root level.

Can anybody help ?

Ok - I've figured it out. I need to declare what my function is before trying to call it - otherwise flash doesn't know what I'm talking about. In case anyone else had a problem like this, here is how the code should be written:

//create new string variable
var hiliname:String = new String("");

//declare what the variable is
hiliname = "ib1";


//declare function called expand2
expand2 = function () {
    trace ("called expand2");
}

//check to see if the variable contains an a,b or c
if (hiliname.substr(1,1) == "a") {
    trace ("found an a");
    expand1();
        
} else if (hiliname.substr(1,1) == "b") {
    trace ("found a b");
//call the function created above if a 'b' is in the variable name
    expand2();
        
} else if (hiliname.substr(1,1) == "c") {
    trace ("found a c");
    expand3();
}

You know, there's another way of declaring a function:

function expand2(){ 
    trace ("called expand2"); 
}

Then, no matter where your code is, before or after the function, it will be called
