Try this

<script language="javascript">

function validate(){

if(document.text1.info.value==""){
alert("Sorry but you didn't put anything in!")
}else{
//DO what you want it they did

}

}
</script>

---------

<form name="text1">
<textarea name="info" rows=8 cols=50 wrap="virtual">
</textarea>
</form>

I didn't test it so sorry if there are errors hehe :D

Hope this helps

Or:
function validate(){

if(document.text1.info.value.length==0){
alert("Sorry but you didn't put anything in!")
document.text1.info.focus()
}else{
//DO what you want it they did

}

}

Thanks to ACJavascript and requestcode! It works now! But i've actually tried the methods u all mentioned earlier on, on some other PCs, but it didn't work. So i'm wondering, is it that certain version of IE doesn't support it?? Impossible, right?

Here are some small edits to the two previous functions.

<html>
<head>
<script language="javascript">

function validate(myform){
if(myform.info.value==""){
alert("Sorry but you didn't put anything in!")
return false;
}
else
return true;

}
</script>

</head>
<body>

<form name="text1" onsubmit="return validate(this)">
<textarea name="info" rows=8 cols=50 wrap="virtual"></textarea>
<input type="submit">
</form>
</body>
</html>
