This code uses a nested IF statement to put a pack of cards into an array of records.
But for some reason the cards arn't going in.. like.. at all?
I've put a document.write piece of code at end to display the card in the first slot and [object Object] appears?

<HTML>
<TITLE>DAT Card Game</TITLE>
<HEAD>
<SCRIPT LANGUAGE="JavaScript">

var Cards = new Array (52)
var Shuffled = new Array (52)

function Card(suit,face)
{this.suit=suit;
this.face=face;
}

function Stack(suit,face)
{
var suit
var face
index=0
count=1
for (count=1;count<=52;count++)
if (count<=39)
{if (count<=13)
{suit='hearts'
face=count
Cards[index]=new Card(suit,face)
index++
count++}
else
{if (count<=26)
{suit='spades'
face=count
Cards[index]=new Card(suit,face)
index++
count++}

else
{if (count<=39)
{suit='diamonds'
face=count
Cards[index]=new Card(suit,face)
index++
count++}}}}
else
{suit='clubs'
face='count'
Cards[index]=new Card(suit,face)
index++
count++}

document.write(Cards[0])
}
</SCRIPT>
</HEAD>
<BODY>
<FORM NAME="MyForm">
<INPUT TYPE="BUTTON" VALUE="stack" onClick="Stack()">
</FORM>
</BODY>
</HTML>

If you copy and paste into notepad and then look at it in your browser you'd see what I mean.
Any ideas?

EDIT: I think my syntax for creating An Array Records is totally wrong just looking through tutorials. Each object in the array has to have a name?

EDIT 2: Ignore this post. I've given up on the Object in Array structure.

I've edited your script and removed some unnecessary code. The face and suit of each card are saved in a multi-dimensional array named Cards. To access each variable use the following syntax:

Cards[1][0] //suit
Cards[1][1] //face
Cards[2][0] //suit
Cards[2][1] //face

and so on. You will notice that after it prints all of the variables in the array, a comma appears at the beginning of the other variables. That is because there is no Cards[0] variables. The Cards array begins at [1].

<SCRIPT LANGUAGE="JavaScript">

function Stack() {
var Cards = new Array(52);
for (i = 1; i < Cards.length; ++i) {
Cards[i] = new Array(2);
}
var suit;
var face;
for (count=1;count<=52;++count) {
if (count<=39) {
if (count<=13) {
suit='hearts';
face=count;
temp = suit + ":" + face;
Cards[count]=temp.split(":");
} else {
if (count<=26) {
suit='spades';
face=count;
temp = suit + ":" + face;
Cards[count]=temp.split(":");
} else {
suit='diamonds';
face=count;
temp = suit + ":" + face;
Cards[count]=temp.split(":");
}
}
} else {
suit='clubs';
face=count;
temp = suit + ":" + face;
Cards[count]=temp.split(":");
}
}
//the following code is only used to test the script
var check = Cards;
document.getElementById('test').innerHTML = check;
}
</SCRIPT>
