E-mail form felt validering fejler

Hej!
Jeg har nedenstående kode, der validere en form. Men scriptet checker ikke korrekt på e-mail feltet. Den kører simpelthen forbi feltet. Nogen der kan spotte fejlen?

E-mail koden:

}
    if(/^\w+([\.-]?\w+)*@\w+([\.-]?\w+)*(\.\w{2,3})+$/.test(form.Email.value))
    {
    alert("Invalid E-mail Address! Please re-enter.");
    return false;
    }

function isReady(form)
{
    if(isFilled(form.Firstname)==false)
    {
    alert("Please fill in your First name");
    form.Firstname.focus();
    return false;
    }
    if(isFilled(form.Familyname)==false)
    {
    alert("Please fill in your Family Name");
    form.Familyname.focus();
    return false;
    }
    if(isFilled(form.Function)==false)
    {
    alert("Please fill in your Function");
    form.Function.focus();
    return false;
    }
    if(isFilled(form.Department)==false)
    {
    alert("Please fill in your Department");
    form.Department.focus();
    return false;
    }
    if(isFilled(form.Country)==false)
    {
    alert("Please fill in Nycomed country");
    form.Country.focus();
    return false;
    }
    if(isFilled(form.Mobilephone)==false)
    {
    alert("Please fill in your Mobile phone No. and include your country code, e.g. +45");
    form.Mobilephone.focus();
    return false;
    }
    if(/^\w+([\.-]?\w+)*@\w+([\.-]?\w+)*(\.\w{2,3})+$/.test(form.Email.value))
    {
    alert("Invalid E-mail Address! Please re-enter.");
    return false;
    }
    if(!document.form.RoomRequired[0].checked && !document.form.RoomRequired[1].checked)
    {

    return false;
