Warning: 3596: Duplicate variable definition.

Problem:
You are using the same variable and Flex/Flash doesn’t like it.
Fix:
Change the name of one instance or unnest your loop.

Bad Code:

var myArray1:Array = [“a”,”b”,”c”,”d”,”e”];
var myArray2:Array = [myArray1];

//This first loop goes through the parent array
for (var i:int=0; i < myArray2.length; i++)
{
//this second loop iterates through the nested array
for (var i:int=0; i < myArray1.length; i++)
{
trace(myArray2[i][i]);
}
}

Good Code:

var myArray1:Array = [“a”,”b”,”c”,”d”,”e”];
var myArray2:Array = [myArray1];

//This first loop goes through the parent array
for (var i:int=0; i < myArray2.length; i++)
{
//this second loop iterates through the nested array
for (var j:int=0; j < myArray1.length; j++)
{
trace(myArray2[i][j]);
}
}

or

var keys:String = “Word”;
for (var i:int=0; i < keys.length; i++)
{
//Code
}

for (i=0; i < keys.length; i++){
//More Code
}
