It is because you are using the JS assignment operator. Typically var a = 123;

You want to be using === since it doesn't do type coercion. As opposed to == which does.

if (value.substring(0,2) === "048") {
    // etc
}

You need == like this. you cant have a single = in an if statement

  if (value.substring(0,2)=="048"){
