You should go in reverse that way you can supply more than one item to remove!

var myArray:Array = ["item1", "item2", "item3", "item4", "item5", "item3"];

// Function function removeItemFromArray( item:String ):Void { trace("Array Original: " + myArray);

// Array Lenght
var i:Number = myArray.length - 1;

// Searches item in array
for ( i; i>=0; i-- )
{
    // Finds item and removes it
    if ( myArray[i] == item )
    {
       myArray.splice( i, 1 );
       trace("Item Removed: " + item );
       trace("Array Updated: " + myArray);
    } 
}

}

// Calls Function removeItemFromArray( "item3" );
