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

Not entirely sure what you want to happen, but maybe try this:

local hi = Instance.new("Hint", workspace)
 
 
while game.Players.NumPlayers < 2 do
    hi.Text = "Invite a player!"
    repeat wait(2) until game.Players.NumPlayers >= 2
 
	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
