A bug that is annoying me a lot! Can someone help me?

What I'm having a problem with is that I made a hammer that allows me to build fences, and so far I'm very happy with the progress! However when I tried it on a local server, it just refuses to work, even printing a string of words, you know, print("Something like this!"). I tried connecting it to the server with a RemoteEvent but it still doesn't work, only on the server! I have no idea why! I might just be blind and stupid but oh well.

I just can't seem to spot the fix. I'm also not sure if it's because of the tool itself or the scripts contained inside because I copied the exact tool but changed the script to just place a brick where you click in the workspace, it works like I expected it to without flaws. Be warned that the script you're about to see is long. 202 lines as of now.

THIS IS CLIENT SIDED!

ATTENTION! Okay, now I've got your attention, I'm just telling you that the next script is server sided.

script.Parent.Build.OnServerEvent:connect(function(plr, fenceSelected, originalPartColor, originalPartTransparency, originalPartMaterial)
	for i = 1, #fenceSelected:GetChildren() do
		local parts = fenceSelected:GetChildren()
		
		if parts[i]:IsA("BasePart") and parts[i].Name ~= "FenceCollision" then
			parts[i].BrickColor = originalPartColor[i]
			parts[i].Transparency = originalPartTransparency[i]
			parts[i].Material = originalPartMaterial[i]
		elseif parts[i]:IsA("BasePart") and parts[i].Name == "FenceCollision" then
			parts[i].CanCollide = true
		end
	end
end)

script.Parent.UpdateStats.OnServerEvent:connect(function(plr, stats, price, level)
	stats.Cash.Value = stats.Cash.Value - price
end)

script.Parent.Print.OnServerEvent:connect(function(plr, message)
	print(message)
end)

Sorry guys, I fixed it. It's because I was trying to access the ServerStorage with a local script.
