This is inside a ClickDetector and a normal script. It works only once and when I try to do this a second time it stops working. ~~lua script.Parent.MouseClick:Connect(function(plr)
if plr.PlayerGui:FindFirstChild("Dialog") == nil then
local gui = script.Parent.Dialog:Clone()
plr.Character.Humanoid.WalkSpeed = 0
gui.Parent = plr.PlayerGui
gui.Core.Disabled = false
script.Disabled = true
wait(1)
script.Disabled = false
end
end) ~~
Considering that you didn't delete the dialog from the script you inserted it in, you probably deleted the dialog in a local script. Whenever you do something in a local script, the server blocks that change and the change only happens for the player who activated the local script. In this case, you deleted the dialog in a local script which means that the server script can not see that the dialog is no longer in the player as the server blocket that change. To fix this, I would recommend you to instead use a local script to insert the dialog. This won't cause any problem as the walkspeed of a character is something that you can change from a local script as the server doesn't have to accept the change for it to work.

Well, duh. Since Dialog is cloned into the PlayerGui, it is no longer nil and the function stops working because Dialog is already there.
It doesn't work after the dialog has been deleted which is when it has been completed
