How to fix Gui giving information to different location?

So, This was made originally for StarterGuis but I wanted to change it to a giver, so I tried tweaking with it myself but ended up not finding a solution. Anyone got an idea on what to do?

Here's the script that gives the information

while true do
	for _, Workspace in pairs(game.Players:GetChildren()) do
		local BossBattleHealthGui = Workspace.GuiGiver.Input:FindFirstChild("BossBattleHealthGui")
		if BossBattleHealthGui then
			BossBattleHealthGui.Frame.Boss.Value = script.Parent.Parent
		end
	end
	wait()
end

Oh, I could tell you that you could watch AlvinBlox. An educational ROBLOX developer on YouTube. ????
