  • Javascript numbers have no comma.

There are at least two syntax errors in the following lines:

var w1 = 42,305 / Math.sqrt(d1) ;
var w2 = 76,63 / Math.sqrt(d2) ;;
  • First: no comma is used , to identify numbers of the type float in JavaScript. For values of the type float we use point .. If the number is integer, leave no comma or dot, even if it is greater than 999
  • Second: do not use the semicolon sign without need, as in your code: ;;
