Can't use a number as a command/ Malformed Number?

So first of all this isn't my admin script, I just needed a way to use GroupIds for obvious reason. But I'm trying to make a Command "3h" basically adds 3 points to a scoreboard, but I have no clue how to do it. Due to the fact of how this script is setup. Is there a way to bypass the malformed number error?

local Admins = {
    "gage7252002"; -- Username example
    17614882; -- User ID example
    -- {GroupId = 0000;RankId = 255;} -- Group example
}
local Prefix = ""

local Players = game:GetService("Players")

local Commands = {}

Commands.print = function(Sender,Arguments)
    local Message = table.concat(Arguments," ")
    print(Message)
end



Commands.3h = function(Sender,Arguments)
    game.Workspace.GuiFolder.OneScore.Value = game.Workspace.GuiFolder.OneScore.Value +3
end


local function IsAdmin(Player)
    for _,Admin in pairs (Admins) do
        if type(Admin) == "string" and string.lower(Admin) == string.lower(Player.Name) then
            return true
        elseif type(Admin) == "number" and Admin == Player.UserId then
            return true
            elseif type(Admin) == "table" then
            local Rank = Player:GetRankInGroup(Admin.GroupId)
            if Rank >= (Admin.RankId or 1) then
                return true
            end
        end
    end
    return false
end

local function ParseMessage(Player,Message)
    Message = string.lower(Message)
    local PrefixMatch = string.match(Message,"^"..Prefix)

    if PrefixMatch then
        Message = string.gsub(Message,PrefixMatch,"",1)
        local Arguments = {}

        for Argument in string.gmatch(Message,"[^%s]+") do
            table.insert(Arguments,Argument)
        end

        local CommandName = Arguments[1]
        table.remove(Arguments,1)
        local CommandFunc = Commands[CommandName]

        if CommandFunc ~= nil then
            CommandFunc(Player,Arguments)
        end
    end
end

Players.PlayerAdded:Connect(function(Player)
    Player.Chatted:Connect(function(Message,Recipient)
        if not Recipient and IsAdmin(Player) then
            ParseMessage(Player,Message)
        end
    end)
end)
