How do I make a button timer in Roblox? - roblox

Question

I was creating an obby in Roblox, and I wanted to make a button that a player could step on to make the platforms in front of them solid. I checked the documentation, and I found nothing that seemed to help. Here is my code: (Ignore e, ee, eee, bt, bt1, bt2, and tch. They are my parts/variables/function names)
bt = game.Workspace.e.SurfaceGui.ButtonTimer
bt1 = game.Workspace.ee.SurfaceGui.ButtonTimer1
bt2 = game.Workspace.eee.SurfaceGui.ButtonTimer2
bt.Text = "hi "
bt1.Text = "hi "
bt2.Text = "hi "
script.Parent.Touched:Connect(function(tch)
if tch.Parent:FindFirstChild("Humanoid") then
game.Workspace.e.Transparency = 0
game.Workspace.e.CanCollide = true
game.Workspace.ee.Transparency = 0
game.Workspace.ee.CanCollide = true
game.Workspace.eee.Transparency = 0
game.Workspace.eee.CanCollide = true
bt.Text = "10"
bt1.Text = "10"
bt2.Text = "10"
wait(1)
bt.Text = "9"
bt1.Text = "9"
bt2.Text = "9"
wait(1)
bt.Text = "8"
bt1.Text = "8"
bt2.Text = "8"
wait(1)
bt.Text = "7"
bt1.Text = "7"
bt2.Text = "7"
wait(1)
bt.Text = "6"
bt1.Text = "6"
bt2.Text = "6"
wait(1)
bt.Text = "5"
bt1.Text = "5"
bt2.Text = "5"
wait(1)
bt.Text = "4"
bt1.Text = "4"
bt2.Text = "4"
wait(1)
bt.Text = "3"
bt1.Text = "3"
bt2.Text = "3"
wait(1)
bt.Text = "2"
bt1.Text = "2"
bt2.Text = "2"
wait(1)
bt.Text = "1"
bt1.Text = "1"
bt2.Text = "1"
wait(1)
bt.Text = "0"
bt1.Text = "0"
bt2.Text = "0"
game.Workspace.e.Transparency = 0.75
game.Workspace.e.CanCollide = false
game.Workspace.ee.Transparency = 0.75
game.Workspace.ee.CanCollide = false
game.Workspace.eee.Transparency = 0.75
game.Workspace.eee.CanCollide = false
else
game.Workspace.e.BrickColor = BrickColor.Red()
end
end)

i have created a timer in my game, I will share the code with you:
local timer = script.Parent
local minutes = 1
local seconds = 9
local adm = script.Parent.Parent
repeat
if seconds <= 0 then
minutes = minutes - 1
seconds = 59
else
seconds = seconds - 1
end
if seconds <= 9 then
timer.Text = "Vote time: "..tostring(minutes)..":0"..tostring(seconds)
else
timer.Text = "Vote time: "..tostring(minutes)..":"..tostring(seconds)
end
wait(1)
until minutes <= 0 and seconds <= 0
