Hi nickos,
checked out both the scripts...the first one seems to b working fine...but you've to check whether the user entered an integer or not...you can convert string to int by using the function parseInt() and to float by parseFloat()...the second script i.e. js2.html takes the input through a form and posts it to another script ( CGI hopefully )...so, JS can't help u much there...hope I'm clear...
