Re: undefined???
rno is not an array. Try removing the [h] in innerHTML=rno[h];

Re: undefined???
Not sure why you are getting the error. It ran for me in IE6.0.
It actually prints all 7 (not 6) numbers generated. The problem is that you only see the last number because:
1) you replace the innerhtml each pass through the loop, and
2) it executes too fast to see each change.
If you only want 6 numbers then remove the '=' from 'h<=6;'.
Take a look at this
Code:
<html>
<head>
<script>
var h=0;
function yaz()
{
document.getElementById('oda').innerHTML = '';
for (h=0;h<=6;h++)
{
var rno = (Math.floor(Math.random()*50)+1);
document.getElementById('oda').innerHTML += rno + '<br>';
}
}
</script>
</head>
<body>
<div id="oda">......</div>
<form>
<input type=button value="print the rand nums" onClick="yaz()">
</form>
</body>
</html>
