I am trying to make a datastore jail, I have jail tool but it doesnt save. How do I do this?

All you have to do is put a BindableEvent "JailEvent" in ServerStorage and this should work

dss = game:GetService("DataStoreService")
jailData = dss:GetDataStore("Jail")
jailTimes = {} 

function jail(player,t)
    if player and t and not jailTimes[player] then
        --records time entered jail and sentence length
        jailTimes[player] = {t,tick()}
        local char = player.Character or player.CharacterAdded:wait()
        wait(1)
        print(player.Name .. " jailed for " .. t .. " seconds")
        char:MoveTo(workspace.Jail.Jail.Position)
        wait(t)
        jailTimes[player] = nil
        if player.Parent==game.Players then
            --removes jail data, only if still in jail
            --(jailTimes also implies whether someone is in jail)
            print(player.Name .. " completed his sentence")
            char:MoveTo(workspace.Jail.Unjail.Position)
            jailData:SetAsync(tostring(player.UserId),0)
        end
    end
end

game.Players.PlayerRemoving:connect(function(player)
    local times = jailTimes[player]
    if times then
        --subtracts time jailed from sentence length for remainder
        --will be jailed again
        local remaining = math.floor( times[1] - (tick() - times[2]) )
        print(player.Name .. " left the game during jail. " .. remaining .. " seconds remain.")
        jailData:SetAsync(tostring(player.UserId),remaining)
    end
end)

game.Players.PlayerAdded:connect(function(player)
    --jails player if has remaining time
    local jailTime = jailData:GetAsync(tostring(player.UserId)) or 0
    if jailTime > 0 then
        jail(player,jailTime)
    end
end)

--any script can jail any player with this
game.ServerStorage:WaitForChild('JailEvent').Event:connect(function(player,t)
    jail(player,t)
end)

Tool

tool = script.Parent
db = false

function touch(hit)
    if db then return end
    db=true
    local char = hit.Parent
    local hum = char:FindFirstChild('Humanoid')
    if hum  then
        local player = game.Players:GetPlayerFromCharacter(char)
        if player then
            game.ServerStorage.JailEvent:Fire(player,30)
            wait(3)
        end
    end
    db=false
end

function sel()
tool.Handle.Touched:connect(touch)
end

tool.Equipped:connect(sel)
