Need help with an array, pls could somebody help8-)

Question

The problem I am currently having is that I want to display variable myblock down 10 times and then test it for collison,
I am using the variable I to store the blocks, pls excuse me as I am new to this, If I manally set the variable i to lets say 1 and 2
and then test for collison it works, but when I use I from the for loop it only detects one object from the array, I think that there is something
probably simple missing such as an extra variable, as you can see from the code I am trying to use the ' i ' to replace for instance addChild(blockarray[1]);
I have set it manually to display two blocks in the code below, collison detection works, but when I want to use a loop to display and test the collison
it only picks up one of the blocks, not sure if this is because variable i is set to 0 in the for loop, any help would be greatly appreciated, this is my first post on here as I'm new to Actionscript, ty for reading8-)
var thehero:BlueBlock = new BlueBlock;
thehero.x=20;
thehero.y=20;
addChild(thehero);
var blockarray = new Array()
for(var i:Number=0;i<10; i++)
// this is where I setup my blocks
var myblock:BlueBlock = new BlueBlock;
blockarray[i]=myblock;
blockarray[i].x = Math.random()*500;
blockarray[i].y = Math.random()*400;
trace(blockarray[i]);
blockarray.push(myblock);
//addChild(blockarray[i]);
addChild(blockarray[1]);
addChild(blockarray[2]);
// Check for keyboard events such as the arrow keys been pressed
stage.addEventListener(KeyboardEvent.KEY_DOWN, myKeyDown);
stage.addEventListener(Event.ENTER_FRAME,blockcollision);
function myKeyDown (e:KeyboardEvent){
if (e.keyCode == Keyboard.LEFT){
thehero.x -=5;
if (e.keyCode == Keyboard.RIGHT){
thehero.x +=5;
if (e.keyCode == Keyboard.UP){
thehero.y -=5;
if (e.keyCode == Keyboard.DOWN){
thehero.y +=5;
function blockcollision(e:Event):void{
if (thehero.hitTestObject(blockarray[1]))
trace("Hit");
if (thehero.hitTestObject(blockarray[2]))
trace("Hit");
