How do I change the form name and description

The form name and description are located in the Properties Panel - in the form settings, under the "basic" tab.

all you need to do in order to change them is:
1- Press on "form" Tab, 


2- Choose the "settings"  tab
3- Open the"General" category


4- the form name and description are the most basic properties of the form - and will be located first.
you can change them at any time. 
when a new form is created, they contain a default value you will need to change.
