Keep getting "expected end to close function" even though i dont need one?

So, i have a big chunky script in the serverscriptservice that handles the movement. (my game is an online boardgame).

Around this bit, where i roll the dice and read which face is up, i keep getting an error: Expected end to close function.

Even if i add an extra end, it doesnt work. Here is that peice of code:

local function isLooking(obj1, obj2)
    local p2pVec = (obj2.Position - obj1.Position).unit
    --check for 2 
    local found = isSide(obj1.CFrame.LookVector, p2pVec)
    if found then 
        return 2
    end
    --check for 5
    local found = isSide(-obj1.CFrame.LookVector, p2pVec)
    if found then 
        return 5
    end

    --check for 3
    local found = isSide(obj1.CFrame.RightVector, p2pVec)
    if found then 
        return 3
    end
    --check for 4
    local found = isSide(-obj1.CFrame.RightVector, p2pVec)
    if found then 
        return 4
    end
    --check for 6
    local found = isSide(-obj1.CFrame.UpVector, p2pVec)
    if found then
        return 6
    end
    --check for 1
    local found = isSide(obj1.CFrame.UpVector, p2pVec)
    if found then
        return 1
    end
end


local function RollDice()
    local ChangeCameraDice = game:GetService("ReplicatedStorage"):WaitForChild("ChangeCameraDice")

    ChangeCameraDice:FireAllClients()

    dice.Anchored = false
    local x = rand:NextInteger(-30,30)
    local y = rand:NextInteger(-30,30)
    local z = rand:NextInteger(-30,30)

    dice.RotVelocity = Vector3.new(x,y,z)
    wait(3)
    return isLooking(dice, upPartDice) 
    dice.Anchored = true
    dice.Position = originalPos
end

And i can give you the full script if you want it.
