After the Signup, you must Check-In to Job/Shift from Job/Shift details screen.
The default configuration set in the V4S Kiosk application is once you search for your name from "Don't see your name below? Signup!" button, you see a signup button to signup for the Job/Shift.
Upon clicking the signup button, the page is reverted to Job/Shift details page with a Check-In and a Cancel button. Click the Check-In button to Check-in to Job/Shift you just signed up for.
If you want to Signup and Check-In from the search volunteer screen itself, please contact your Volunteer Coordinator/Manager and request for the same. We can make the configuration changes and allow the volunteer to signup and Check-In from the search volunteer screen itself.
