Forms View
You can view and complete forms for the selected task step.
The Views button is the default view in the Tasks tab. From the regular and web task lists, you can view inputs as read-only from the Task History tab. To see a list of forms, go to the Input drop-down list.
Note: HTML5 forms are not supported in the Web Task List.
Note: You must have authorization to perform certain actions in the ActiveX Task List. If you cannot work in this area, you may not have the permission to do so, but you may still view the contents.
Web-based (HTML) Forms in the Task List
You can view forms that have been cancelled or submitted. If a form has been changed or deleted outside of the Task List, the form you view may not accurately reflect the original version.
Note: 
If the Form icon is enabled, you can view completed forms.
If the Form icon is enabled, you can view completed forms.Cancelled Forms
If a form has been canceled before it was submitted, you are able to view the initial form fields only, not any entries that an operator has made.
Submitted Forms
If a form has been submitted (that is, fully completed), then you are able to view the form's contents as it appeared during submission. You cannot, however, submit the form again.
