Seconds ago, it was working, and I did not change anything. My web app is a simple web-app. Javascript is responsible for form validation before it redirects it to the servlet. What did I do wrong?

Form validation is not validating. I am a novice programmer, so please help. 

```
// form-validation (javascript)
function validateForm() {
    var firstname = document.forms["myForm"]["förnamn"].value;
    var lastname = document.forms["myForm"]["efternamn"].value;
    var address = document.forms["myForm"]["address"].value;
    var email = document.forms["myForm"]["email"].value;
    var news = document.forms["myForm"]["news"].value;

    if (firstname == null || firstname == "") {
        alert("Var god och fyll i alla fält!");
        return false;
    } else if (lastname == null || lastname == "") {
        alert("Var god och fyll i alla fält!");
        return false;
    } else if (address == null || address == "") {
        alert("Var god och fyll i alla fält!");
        return false;
    } else if (email == null || email == "") {
        alert("Var god och fyll i alla fält!");
        return false;
    } else if (email.indexOf("@hotmail.com") === -1) {
        alert("Skriv in en korrekt mail-address. exempel@hotmail.com");
        return false
    }
}
