number to string viceversa

[Sayantandutta]

var aaa= formName.subtotal.value;
  var bbb = formName.Hour.value * formName.Rate.value;
  formName.subtotal.value= parseFloat ('aaa') + parseFloat ('bbb');

Trying to print subtotal but getting error message as Nan

... = parseFloat('aaa') + parseFloat('bbb');

There should not be quotes around your variable names.

A more succinct method is to use implied conversion:

var aaa = formName.subtotal.value;
var bbb = formName.Hour.value * formName.Rate.value;
formName.subtotal.value = +aaa + bbb;
