Value doesn't change client/server side?

This script is a normal script inside the server script service. The value I am trying to change is inside the player. (player service object)

--p is the player object inside the player service, not the player name.
VoteEvent.OnServerEvent:Connect(function(p)--When the vote event that comes from the client with the player object(p)
	local Players = game:GetService("Players")
	local VotedValue = p:WaitForChild("Voted")
	VotedValue.Value = true--No error but the value stays the same.
end)

thanks.

VoteEvent.OnServerEvent:Connect(function(p)
   local success, errormessage = pcall(function()
    local Players = game.Players
    local VotedValue = p:WaitForChild("Voted")
    VotedValue.Value = true
    end)
if not success then
warn(errormessage) --prints what is the problem, if there's a problem
end
end)
