Hello! I’m trying to make it so that there’s a random number generator and then it chats out the random number but I don’t know how to make it so I can put the code number into the string.

local cha = game:GetService("Chat")
local codenumber = math.random(1000,1999)

wait(5)
cha:Chat(script.Parent, "code number here", Enum.ChatColor.White)

wait(5)
cha:Chat(script.Parent, tostring(codenumber), Enum.ChatColor.White)
