Hi,

How can I check if the cookie MemEmail exist?

I am getting an error on this line.

 if (document.cookie.indexOf('MemEmail') = -1)

function submitForm(theForm) {
  var errorMsg = "";
  var errorField = null;

  if (document.cookie.indexOf('MemEmail') = -1) 
  {
 
  if (theForm.TxtEmail.value == document.FRMAcc.TxtEmail.defaultValue) {
    errorMsg += "Email field is Empty\n";
    if (errorField==null) errorField=theForm.TxtEmail;
  }
  
  if (theForm.TxtPassword.value == document.FRMAcc.TxtPassword.defaultValue) {
    errorMsg += "Password field is Empty\n";
    if (errorField==null) errorField=theForm.TxtPassword;
  }

  if (errorMsg != "") {
    errorMsg += "---------------------------------\n\n";
    errorMsg += "Please correct the problem(s)\n";
    alert(errorMsg );
    errorField.focus();
    return false;
  }
  }
  return true;
}
