Can the local script acess the serverscriptservice?

Hello I want to make a start and a stop button that will trigger the intValue in ReplicatedStorage. And in the serverscript service it checks is the intvalue is 1 or 0 if it is 1 it start, 0 it stops. But I am having an issue with the start and stop button not working please help me on my script. And yes I tried bool value.

local StartButton  = script.Parent.StartButton
local StopButton = script.Parent.StopButton
local UniValue = game.ReplicatedStorage.UniValue

StartButton.MouseButton1Down:Connect(function()
	UniValue = true
	StartButton.Visible = false
	StopButton.Visible = true
end)

StopButton.MouseButton1Down:Connect(function()
	UniValue = false
	StopButton.Visible = false
	StartButton.Visible = true
end)

My Gui script. So my question is Can the local script acess the serverscriptservice and the bool value? Thanks
