So, I’m making a game and u have to hold a building for 100 seconds to win, the cap is 100, I’m trying to make a chat command that changes the cap to another number, when I try to do it it gives me this error:

I tried to use tonumber(args[1]) but it still doesnt work and gives me the same error
Script Im using:
_G.termCap = 100
local prefix = ":"
local admins = {your_user_id_here}
local function checkIfAdmin(plr)
local isAdmin = false
for i,v in pairs(admins) do
if plr.UserId == v then
isAdmin = true
end
end
return isAdmin
end
commands.cap = function(plr, args)
--local newCap = tonumber(args[1])
_G.termCap = args[1]
wait()
game.ReplicatedStorage.gameStuff.termCap.Value = _G.termCap
end
game.Players.PlayerAdded:Connect(function(plr)
plr.Chatted:Connect(function(message, recipient)
if checkIfAdmin(plr) == true then
local split = message:split(" ")
local fullcmd = split[1]
local cmd = fullcmd:split(prefix)
local cmdName = cmd[2]
cmdName = string.lower(cmd[2])
if commands[cmdName] then
local args = {}
for i = 2, #split, 1 do
table.insert(args,split[i])
end
commands[cmdName]()
end
end
end)
end)
