Answer:
First off, it's HTML, and not a program. Opening and closing HTML tags are required. Body tags are also required inside the HTML tags. Your table tags belong inside the form tags, not as you have them. Your opening form tag has been misspelled as "from" - this needs correction. Form tags have required action and method attributes; these attributes can be null, for example, action="". You need JavaScript to parse the values and return the result - for example: <html> <head> <script type="text/javascript"> function validate(){ var rslt = new Number(); var a=new Number(document.getElementById('1').valu… var b=new Number(document.getElementById('2').valu… var c=new Number(document.getElementById('3').valu… rslt=a+b+c; alert("Result: "+rslt); } </script> </head> <body> <form action="" method=""> <table border="1"> <tr> <td><input type="text" id="1" value="20"></td> <td><input type="text" id="2" value="30"></td> <td><input type="text" id="3" value="40"></td> </tr> <tr> <td colspan="3" align="center"><input type="button" onclick="validate();" name="" value="Submit"></td> </tr> </table> </form> </body> </html>
