Required Fields Email and Print

Hi,

I have created a form in Livecycle Designer 8.2. I have set the fields Required in Object, Value, User Entered Required.

In each required field I have added in Javasript using the Exit event:

if (Name.rawValue != null){
Name.mandatory = "disabled";
}

Now when I click print any fields not completed are shown in Red which is great.

But I now need it to do the same on the Submit By Email button. I have tried adding the same javascript but using the PreSubmit event but when I click the email button it just open the email screen.

Any suggestions.

Thanks

Wayne
