Before you start 
            The Manage user-defined forms to display and collect data permission is required.
            
                
            
        
        Here's what to do 
- 
                Click a user-defined form.
            
- 
                Create a space in the form to insert the electronic signature. For example, you
                    may need to add a row.
            
- 
                In the Field Chooser menu, click ESignature and then find the desired set of
                    four ESignature fields in this list. 
            
- 
                Drag and drop the desired main ESignature field to be used for capturing the
                    assignee's input. 
            
- 
                Click the field to display the Selected Element Properties section at the
                    bottom of the form.
            
- 
                In the Mandatory drop-down list, click Yes.
                It is not mandatory to make the main ESignature field mandatory but it is a
                    good practice. You will probably want to force the assignees to provide an
                    electronic signature and have it validated when they complete the form.  
- 
                Click Save.
