I am trying to make a round script for the seconds to count down but it isn't working help?

You forgot to close the space. Code in Lua cannot have spaces.

local roundLength = 5
local intermissionLength = 10 -- You had a space: 'intermission length'
local inround = game.ReplicatedStorage.InRound
local status = game.ReplicatedStorage.status

local lobbySpawn = game.Workspace.GameAreaSpawn



local function RoundTimer()
    while wait() do
        for i = intermissionLength, 1, -1 do
            inround.value = false -- You have to correspond to the variable. You wrote 'InRound'
            wait (1)
            status.value = "Intermission: "..i.." seconds left!"
        end
        for i = roundLength, 1, -1 do
                InRound.value = false
                wait (1)
                status.value = "game: "..i.." seconds left!"  
        end
    end
end
spawn(RoundTimer)

This should work! Hopefully it helped!
