the html is better ))

as for javascript... my english is not good. it seems i used wrong word when wrote about "pair". i think it would be much better if somebody explain everything to you in right good english

anyway, here is the code which works:

Code:

<!DOCTYPE html>
<html>
<meta http-equiv="Content-type" content="text/html; charset=iso-8859-1"/>
<title>enter you number</title>
<script type="text/javascript">
function formValidator(){
var max = 99;
var min = 1;
var val = parseInt(document.forms['myform'].elements['firstname'].value);
var res = document.getElementById('result');
if((val <= min) || (val >= max)){res.innerHTML = "Wrong number!";}
else{res.innerHTML = "The number is between 1 and 99";}
}
</script>
</head>
<body>
<center>
<hr />
<h1>enter your number</h1>
<hr />
<p>Note: all fields are mandatory.</p>
<form name="myform">
enter number between 1-99999: <input type="text" name="firstname" />
<br /><br />
<input type="button" value="Check it up" onclick="formValidator()" />
<br /><br />
<div id="result"></div>
</form> 
</center>
</body>
</html>

1. why do you tell the browser that your document is xhtml when you are writing html?
2. where did you learn that dom manipulating scripts are to be put on the document head if at all?
3. why do you call for var RunnerID = document.getElementById('RunnerID'); when there's no RunnerID element anywhere in your document except in your imagination?
4. the same question for: var EventID = document.getElementById('EventID');- what EventId? Where is it?
5. Why are you closing the "}" you didn't open?
6. Why do you open brackets ({) you don't want to close ?
7. parseFloat(textBox.value); -what textBox value, where textBox.value?! are you seing things?
8. if ( isNaN(boxValue) ; what if isNaN for boxValue? -there is no boxValue!

The reason I'm replying to you was not to answer your question, even though I already answered it, - but to ask you, where on earth did you get the guts to ask 'why wont >>this<< work' ?!
