This is needed to convert the value from a string to a number.*/ </script> </head> <body> <form name="form1" action=""> Number 1 (enter number):<br /> <input type="text" id="number1" value="" size="40" /><br/> Number 2 (enter value in dollars, e.g. 2.50) :<br /> <input type="text" id="number2" value="" size="40" /><br/> Result:<br /> <input type="text" id="result" value="" size="40" /><br/> <input type="button" id="Calculate" value="Calculate" onclick="calcform()" /> <input type="reset" id="reset" value=" Clear "/> </form> </body> </html> Passing the value to another page is another matter. If you need help to do this I can post the code for how I do it - it does need some more JavaScript -- Trevor Lawrence Canberra Microsoft MVP - FrontPage MVP Web Site http://trevorl.mvps.org |
