hey people I have a javascript validation code for a form, it validates the form, then it redirects them to the next page without requiring them to enter the correct information. please help me out.

Thank you ahead of time

here is the code:
Code:
function validateFormOnSubmit(theForm) {
var reason = "";

reason += validateUsername(theForm.username);
reason += validatePassword(theForm.password);
reason += validateConfirmPassword(theForm.confirmpass);
reason += validateEmail(theForm.email);
reason += validateConfirmEmail(theForm.confirmemail);
reason += validateSiteTitle(theForm.sitetitle);

if (reason != "") {
alert("The following field(s) need to be corrected:\n\n" + reason);
return false;
}

return true;
}

function validateUsername(fld) {
var error = "";
var illegalChars = /\W/; // allow letters, numbers, and underscores

if (fld.value == "") {
fld.style.background = 'Yellow';
error = "You didn't enter a username.\n";
} else if ((fld.value.length < 1) || (fld.value.length > 50)) {
fld.style.background = 'Yellow';
error = "The username is the wrong length.\n";
} else if (illegalChars.test(fld.value)) {
fld.style.background = 'Yellow';
error = "The username contains illegal characters.\n";
} else {
fld.style.background = 'White';
}
return error;
}
