pls dont delete my question :( I used this;
script.Parent.Touched:Connect(function(h) if h.Parent:FindFirstChild("Humanoid") then game.Workspace.Gravity = 005 end end)
I want a timer that 20 seconds later gravity becomes normal. Can someone help, please?

Please research ahead of time. The answer to your problem was a simple wait() function; you would've found the needed information easily.
Furthermore, "005" is recognized as an integer of 5 making the zeros redundant. If you were looking to assign a floating-point value, you must represent the data as a decimal: 0.05.
However, this would drastically affect the gravity.
