Help, I'm making an online battle game and am currently making the text version just to get the equations working. I keep getting this error:

I can't seem to find what the error is. Can anyone help me. Here's my code:

<script type="text/javascript">
var name=document.player.name.value;
var element=document.player.element.value;
var level=document.player.level.value;
var health=document.player.health.value;
var magic=document.player.magic.value;
var speed=document.player.speed.value;
var attack=document.player.attack.value;
var defense=document.player.defense.value;
var name1=document.enemy.name.value;
var element1=document.enemy.element.value;
var level1=document.enemy.level.value;
var health1=document.enemy.health.value;
var magic1=document.enemy.magic.value;
var speed1=document.enemy.speed.value;
var attack1=document.enemy.attack.value;
var defense1=document.enemy.defense.value;
function attack()

Well, it's doing var name=document.player.name.value; before the form has been created (before it in the page), so it doesn't exist therefor has no properites.

Leave the variable declarations where they are but initialise them inside a function that you can call onload.

Thats one problem, but that still doesn't fix that error message.

You need to delay all those assignments to after the form has been parsed. So, move them into the load event.

Thanx guys, you helped me out. The one thing I changed is used id instead of name and it fixed everything. (not my idea, suggested by someone else)
