 Ok, what i want to do(plz copy the code paste into notepad or something and open in an internet browzer) is...

This is a RuneScape calculator for my website. I need help on the Javascript thing. You DO NOT need to know what RuneScape is to help me :).

Ok what i want it to do is...

tell them how much experience in a skill they need to the next level(woodcutting in this case as it's the smallest skill) then go and tell them how much logs to cut down.

To give you a virutal example here it is:

I need 400 exp, and I want to chop down Common trees. The calculator will calculate the amount of trees to cut down(400 divided by 25). Now here is the code(so far):
Code:
 
<html>
<head>
<script language="javascript">
function setvariable()
{
var exp_needed = window.document.form.exp_needed.value
}

function getexp_needed()
{
var exp_needed = window.document.simple_form.get_exp.value - window.document.simple_form.total_exp.value
exp_needed = exp_needed
window.document.form.exp_needed.value = exp_needed
}

</script>
</head>
<body>
<form name="form">
</td>
<P><B>You need this much experience: </B>
<input type="text" size="13" name="exp_needed" readOnly="yes" value="0" onChange="setvariable()"></P>
</form>
<table align="center" border="1">
<tr>
<th>What you need to do</th>
<th>What level you want</th>
<tr>
<td>
<form name="simple_form">
<P><B>Your total exp:</B>
<input type="text" size="13" name="total_exp" value="0"  onChange="getexp_needed()"></P>
<table border="1" align="center">
<tr>
<th>Number</th>
<th>Name</th>
<th>Lvl.</th>
<th>Exp.</th>
</tr>
<tr>
<td>
<script language="javascript">
<!--hide
[COLOR=red]document.writeln(exp_needed/25)[/COLOR]
//-->
</script>
</td>
<td>Common tree</td>
<td>1</td>
<td>25</td>
</tr>
<tr>
<td></td>
<td>Oak tree</td>
<td>15</td>
<td>37.5</td>
</tr>
<tr>

Can n e one help? I've tried almost everything

1 in 10 people understands binary, the other 1 doesn't
[ * * * * * * ]
 var new_needed = exp_needed / 25 ;
document.write(new_needed);

I would use two seperate lines here, one for the working out, then a simple write line to give the already worked out variabel (i called it new needed but you call it what you want)
