Volunteer signup website We are having a festival and need a way for volunteers to signup. I have already created the login/registration system. The volunteers will login and then have a choice of days to choose from (Thursday to Sunday)they are then taken to a page that offers them the opportunity to choose from 5 different shifts (shift 1, shift 2,...,shift 5). Then they go to a page where all the jobs for that shift are listed with radio buttons and they submit the form which gives them a success msg and takes them back to the original page where they can select another shift or logout. Also, each shift only needs so many volunteers, for example, beer dispensing shift 1 needs 12 volunteers. I would like to have a table that lists the total volunteers needed for each shift. After the shift has all the volunteers needed, that radio button would not display on the form. So, if beer dispensing had 12 volunteers signed up, it would not be displayed as an option to be selected. Also, I would need the login info to the form the user submits so that we know who has signed up for each shift. A report would also be needed to display who is working each shift. I have a spreadsheet listing all the volunteer days, shifts, jobs.
