Given that I am viewing the form submissions of a form
When I click on the checkbox button associated with a submission
Then the 'Delete' button at the top right corner of the table is enabled

When I click the 'Delete' button
Then the Modal window pops up with a message 

          'Are you sure you want to delete the selected form submission?'

And I see two buttons labeled 'Cancel' and 'Delete'

When I click 'Cancel' button 
Then the modal window closes

When I click 'Delete' button
Then the system completes the process of deleting the form submissions
And returns to the Form submissions page with the updated list
