Why isn't my script setting a BoolValue correctly?

I have a script that is supposed to set some variables and such, it's pretty simple. Except when I get to the part of the code that it supposed to change a BoolValue, then it for some reason doesn't wanna work.

local player = game.Players.LocalPlayer
local character = player.Character
local m = workspace.Robot.HumanoidRootPart
local beat = script:WaitForChild("Heartbeat")
local chase = script:WaitForChild("Chase")
local playChase = script.PlayChase

playChase.Value = false

local cam = workspace.CurrentCamera

beat.PlaybackSpeed = 0.8
beat.Looped = true
beat.Volume = 1
beat:Play()

player.CameraMode = Enum.CameraMode.LockFirstPerson

while true do
	if character then
		local rp = character.HumanoidRootPart
		local distance = (m.Position - rp.Position).magnitude
		if rp and distance < 40 then
			-- The npc is near
			playChase.Value = true
			beat.PlaybackSpeed = 1
			beat.Volume = 1.5
			print("Near")
		elseif rp and distance > 40 then
			-- You're safe
			print("Far")
			playChase.Value = false
			beat.PlaybackSpeed = 0.8
			beat.Volume = 1
		end
	end
	wait(.1)
end

local function ChaseIsOn()
	if playChase then
		-- If playChase is true then play the chase track --
		chase:Play()
	else
		-- if playChase is not true then we hold off till later
		chase:Stop()
	end
end

playChase.Changed:Connect(ChaseIsOn)

It's on lines 25 and 32. For some reason it doesn't want to set the variables, yet everything else works as intended. The "ChaseIsOn" function never fires, and when I test it in studio, the BoolValue never changes. I still see the console print "Near" as it should which is also throwing off.

Is it something quick and super easy to fix, or am I overlooking something? I think it may have something to do with the fact that it's in a while loop and it's continually running over and over, but I don't understand why that would be a problem. Can anyone figure this out? Any help is appreciated.
