OnPart function won't change the value of a boolvalue?

When a player walks over a spawn it sets a bool value (IsInMatch) to false. When the bool value is set to true the GUI is Invisible, but when the boolvalue is false the GUI is visible. Although, that's not the problem. the problem is that when I walk over my spawn, it won't change the value of the boolvalue, hence letting the GUI not disappear.

here is the local script inside the spawn:

local IsInMatch = game.Players.LocalPlayer.IsInMatch

function OnTouch(part)
	IsInMatch.Value = true
end

There's not Touched event to allow the function to Run, write this to solve your issue

local IsInMatch = game.Players.LocalPlayer.IsInMatch

function OnTouch(part)
    IsInMatch.Value = true
end

local Spawn = script:FindFirstAncestor("Spawn")
Spawn.Touched:Connect(function(hit)
   if (hit ~= nil) then
      OnTouch(Spawn)
   end
end)
