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>
