Live Cycle Validation and Focus not working

Hello

I have a problem with the validation and the focus function when sending a form. I have two dynamic forms. I created a send pdf to E-mail custom button with a click event and I used a script that I found on a blog:

f(Textfeld4.rawValue != null)

{

    //fill in e-mail

    var Mailto = Textfeld4.rawValue;

    //var Mailto = "test@test.de";

    //fill in subject

    //var YourSubject = Formular1.s1.subject.rawValue;

    var YourSubject = Textfeld3.rawValue;

    //fill in message

    //var YourMessage = "Content PDF:\r" + "Field content: " + Formular1.s1.inhalt.rawValue + "\rName: " 

    var YourMessage = " "; 

    var Mail = "mailto:" + Mailto + "?Subject=" + YourSubject + "&Body=" + YourMessage;

    //cSubmitAs: "PDF" send the pdf as attachment

    //cSubmitAs: "XML" send the pdf as xml-attachment

    event.target.submitForm({

    cURL: Mail,

    bEmpty: true,

    cSubmitAs: "PDF"

    });

}

With these settings:

On the first form, the validation and the focusing to the first blank fields are working perfectly. I used the same script on another dynamic form and the validation and focusing are not working. I used the same script with little changes but the validation and focusing aren't working. The fields are not being focused and are not colored red. Did I miss something?

Kind regards
