How to solve an impossible WalkSpeed error?

--Varaibles
char = script.Parent;
hum = char:WaitForChild("Humanoid");

UIS = game:GetService("UserInputService");
RS = game:GetService("ReplicatedStorage");
Remote = RS:WaitForChild("Remote");
UpdateWalkSpeed = Remote:WaitForChild("UpdateWalkSpeed");

speeds = {}
numSpeeds = 0;
callRestart = false;

function Speed()print("1")
	numSpeeds = numSpeeds + 1;
	
	local function Restart() print(2)
		for i, speed in pairs(speeds)do print(3)
			if(numSpeeds > 1)then print("call restart")
				callRestart = true;
				numSpeeds = numSpeeds - 1;
				
				break;
			end
			
			if(callRestart == true)then print("restarting")
				callRestart = false;
				
				if(i > 1)then
					UpdateWalkSpeed:FireServer(hum.WalkSpeed / speeds[i - 1]);----WON'T PUT THIS VALUE IN NO MATTER WHEN
					print(hum.WalkSpeed)print("/")print(speeds[i-1])print(hum.WalkSpeed / speeds[i - 1])
				end
				print("WALKSPEED:" .. hum.WalkSpeed)
				
				Restart();
				
				break;
			end
			
			if(i > 1)then
				UpdateWalkSpeed:FireServer((hum.WalkSpeed / speeds[i - 1]) * speeds[i]);
				print(hum.WalkSpeed / speeds[i - 1])print("*")print(speeds[i])print((hum.WalkSpeed / speeds[i - 1]) * speeds[i])
			else
				UpdateWalkSpeed:FireServer(hum.WalkSpeed * speeds[i]);
				print(hum.WalkSpeed)print("*")print(speeds[i])print(hum.WalkSpeed * speeds[i])
			end
			
			wait(0.05 * i);
			
			if(i == #speeds)then
				numSpeeds = numSpeeds - 1;
			end
		end
	end
	
	Restart();
end

UIS.InputBegan:Connect(function(input)
	if(input.KeyCode == Enum.KeyCode.LeftShift and
		hum.WalkSpeed ~= 0)then print("firing")
		Speed();
	end
end)

--Body
for i = 1, 4 do
	table.insert(speeds, i, 1 + (0.35 / i));
end

table.insert(speeds, 5, 1);

The line that says, WON'T PUT THIS VALUE IN NO MATTER WHEN, is the line with the error. The code seemingly updates the player walkspeed, identical to every other time the script does it. However, the feedback shows the following:

restarting 18.800001144409 / 1.175 16.000000973965 WALKSPEED:18.800001144409

The code understands to turn the walkspeed back to 16. It does so, but then, the very next second, it turns back to 18.8. I've tried adding waits everywhere, putting the UpdateWalkSpeed:FireServer in a separate function and calling it from far away, moving it. But no matter how I divide or where I move that line of code ``UpdateWalkSpeed:FireServer(hum.WalkSpeed / speeds[i - 1]); It doesn't change its flawed result. Please, I've been up for the last 3 hours (it's 2:41 am currently) pondering what the possible source of this error could be. I would appreciate it more than anything if someone else knows the solution. Thanks!! :)

i think i changed your code from kinda java i guess to lua so this should work, just removed all the ;
