If Statement Only Executing Else Part

I have a simple program that validates a sign up form. Basically I reach a problem when one of my "if" statements can only execute the "else" part. If I change the form so that "if" is executed, nothing happens. Below is my code:

function verifyprocedure() {
    var originalpassword = document.getElementById("password").value;
    var checkpassword = document.getElementById("verifypassword").value;
    var emailcheck = document.getElementById("email").value;
    var male = document.getElementById("gendermale");
    var female = document.getElementById("genderfemale");
    var form = document.getElementById("signup");
    var emailexist = /^[a-zA-Z0-9._-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,4}$/;
    if (originalpassword == checkpassword) {
        if (originalpassword.length < 9) {
            if (emailexist.test(emailcheck)) //this is the statement that does not work
            {
                alert("Hello World!"); //this is whats supposed to be executed
            } else { //this is successfully executed
                $("#email").notify("Please enter a valid email address.");
            }
        } else {
            $("#password").notify("Passwords must have at least 9 characters.");
        }

    } else {
        $("#verifypassword").notify("Passwords do not match.");
    }
}
