Why aren't some parts of DataStore working?

Why doesn't this XP and XpNeeded and debounce DataStore work? PS. I put my DataStore keys hidden, so I made them random.

RebirthData = game:GetService("DataStoreService"):GetDataStore("ddddeee232")

  

XpData = game:GetService("DataStoreService"):GetDataStore("trreeee23232")

KillsData = game:GetService("DataStoreService"):GetDataStore("awesoemee22")

  

DeathsData = game:GetService("DataStoreService"):GetDataStore("day123334")

  

LvlData = game:GetService("DataStoreService"):GetDataStore("Stroin11112")

  

XpnData = game:GetService("DataStoreService"):GetDataStore("Store212")

  

Code1Data = game:GetService("DataStoreService"):GetDataStore("Data333")

if tag then

local killer = tag.Value

if killer then

killer.leaderstats.Kills.Value = killer.leaderstats.Kills.Value + 1

killer.XP.Value = killer.XP.Value + math.random (5,10)

Try putting a pcall function so the script wont error and break down like this

local s,e = pcall(function()
dataname:SetAsync("key"..UserId,datahere) --change dataname,key and datahere, and maybe UserId
end)
