I have a scenario, where we have 3 fields(optional - Single line Field) Preferred location 1, Location 2, Location 3 When user fill form based on the field value sending email to the user.

If user filled 1,2 and 3 fields then no issue in the email working fine. But if user filled only 1 and 2 (or any 2 fields between them), then send email Failed.

Noticed it is because $form_Location3$ value is empty.

Any suggestion/feedback that why $form_Location3$ with empty value giving error as 'System.NullReferenceException',?
