Hello! Basically, I’m trying to make a script, once you type /jail then, apart from the first 5 words, /jail it should detect plr name, but how would I make like, it just doesn’t detect the 10 letter something like >= 10 ? anybody can help?
SCRIPT

game.Players.PlayerAdded:Connect(function(plr)
	game.ReplicatedStorage.Events.Notifcation:FireAllClients("Player Connected", plr.Name.." Joined", 7)
	plr.Chatted:Connect(function(chat)
		if plr:GetRankInGroup(5221664) >= 252 then
			if string.lower(string.sub(chat, 1, 7)) == "/unjail" then
				local letter1 = string.sub(chat, 10)
				game.Players:FindFirstChild(letter1):WaitForChild("Status")["Prison Time"].Value = 0
			elseif  string.lower(string.sub(chat, 1, 5)) == "/jail" then
				local letter1 = string.sub(chat, 10)
				game.Players:FindFirstChild(letter1):WaitForChild("Status")["Prison Time"].Value = 300
			end
		end
	end)
end)

string.len() returns the length of the string, so you could, for example, check from character 6 to the length of the string to pick up any arguments.

Hey, I could sort it out using chat:split(" ")

#4

If you’re going to use string.split() instead of string.sub() then you can skip the first value in the returned array as, at that point, string.sub() is not nessecary

#5

I’m not sure is this what you need but, here:

if chat:lower():sub(1,5) == "/jail" then
    local Name = chat:sub(7)
    print(Name)
end

This should output the name correctly.

Try This

game.Players.PlayerAdded:Connect(function(plr)
	game.ReplicatedStorage.Events.Notifcation:FireAllClients("Player Connected", plr.Name.." Joined", 7)
	plr.Chatted:Connect(function(chat)
		if plr:GetRankInGroup(5221664) >= 252 then
			if string.lower(string.sub(chat, 1, 7)) == "/unjail" then
				local letter1 = string.sub(chat, 9)
				game.Players:FindFirstChild(letter1):WaitForChild("Status")["Prison Time"].Value = 0
			elseif  string.lower(string.sub(chat, 1, 5)) == "/jail" then
				local letter1 = string.sub(chat, 7)
				game.Players:FindFirstChild(letter1):WaitForChild("Status")["Prison Time"].Value = 300
			end
		end
	end)
end)
