Newbie Help! with pivot table and text results

I thought by standardizing column headers on multiple tabs I could use a pivot table to create a Master List of Volunteers. The goal is to have pivot table page show Event/Date-Location/Task/Name. Then secondary purpose is to be able to filter names field so I can determine what Tasks on volunteer list still need someone assigned. Help please - this is to assist a failing minor baseball association. Many thanks - and please pardon my VERY intermediate skillset (read: novice+).. please attached spreadsheet

yes kind of like that - now is there a way I can get same results using all tabs - then the pivot table on its own page...?
