Hey!
Here is the line of Script I am having an issue with:
profile.Data.XP += 1
XP.Value = profile.Data.XP
print("Given XP")
The error it’s giving me is ‘attempt to perform arithmetic (add) on nil and number.’ I am using ProfileService to make my level system, and I’m testing with my XP part to see if it works and it gave me that error. Let me know how I can fix this. If you need more script to be shown, let me know.
Thanks a lot.
Need to use XP.Value += 1 just XP is an instance, but since your error is stating nil you might have other issues present.
Ah unless profile.Data.XP is part of a table where XP is not a valid member of Data.
You probably need to set XP to a number like 0 or 1 before adding on to it.
local saveStructure = {
Points = 0;
Rubys = 0;
Deaths = 0;
Kills = 0;
playTime = 0;
Wins = 0;
Level = 0;
XP = 0;
RequiredXP = 0;
}
Here is the table I have

Can you also print(profile) near your problem line?
It prints this:
{
["Data"] = ▶ {...},
["GlobalUpdates"] = ▶ {...},
["KeyInfo"] = Instance,
["KeyInfoUpdated"] = ▶ {...},
["MetaData"] = ▶ {...},
["MetaTagsUpdated"] = ▶ {...},
["RobloxMetaData"] = {},
["UserIds"] = {},
["_hop_ready"] = false,
["_hop_ready_listeners"] = ▶ {...},
["_is_user_mock"] = false,
["_load_timestamp"] = 37977.248036869,
["_profile_key"] = "Player_1056152894",
["_profile_store"] = ▶ {...},
["_release_listeners"] = ▶ {...}
}
This is because you haven’t used the profile:Reconcile() function in PlayerAdded function, because when a new player joins the game, the profile.Data table would be empty. profile:Reconcile() fixes that problem by filling it with the data structure you provided at the beginning of the script.
Another solution you could do is by referencing key values by brackets instead.
So this:
profile.Data.XP += 1
Should be instead this:
profile.Data["XP"] += 1
(also i would highly recommend reading the profileService documentations first)
Thank you, the profile:Reconile() Helped a lot. Here is my script that I did:
local function PlayerAdded(player)
local profile = PlayerProfileService:LoadProfileAsync("Player_" ..player.UserId, "ForceLoad")
if profile ~= nil then
profile:AddUserId(player.UserId)
profile:Reconcile()
profile:ListenToRelease(function()
cachedProfiles[player] = nil
player:Kick("Your data loaded Remotly, please rejoin.")
end)
if player:IsDescendantOf(Players) then
cachedProfiles[player] = profile
playerDataLoaded(player)
else
profile:Release()
end
else
player:Kick("Data did not load, please rejoin or report in the links below of game Description.")
end
end
for _, player in ipairs(Players:GetPlayers()) do
spawn(function()
PlayerAdded(player)
end)
end
Players.PlayerAdded:Connect(PlayerAdded)
Glad that helped!
Also i would recommend you using task.spawn or coroutine.wrap(PlayerAdded)(player) instead, since spawns are VERY outdated and inefficient to use.
