CanCollide still equals false?

local hi = Instance.new("Hint", workspace)

while true do

while game.Players.NumPlayers < 2 do
    hi.Text = "Invite a player!"
    repeat wait(2) until game.Players.NumPlayers >= 2
e

for w = 30,0,-1 do
    hi.Text = "Intermission : "..w
    wait(1)
end

game.Workspace.BlueFront.CanCollide = false
game.Workspace.RedFront.CanCollide = false
game.Workspace.Baseplate.CanCollide = true

for r = 200,0,-1 do
    hi.Text = "Round "..r
    wait(1)
end


game.Workspace.BlueFront.CanCollide = true
game.Workspace.RedFront.CanCollide = true
game.Workspace.Baseplate.CanCollide = false
wait(5)
end

The problem is that the BlueFront, RedFront, or Baseplate won't disable CanCollide when told
