Why is TweenSize Acting Funky?

So this chunk of script is running ina LocalScript and is triggered by a RemoteEvent (as shown) tht is fired in a script in ServerScriptService. The part that I'm emphasizing is the area that is using TweenSize. For some reason, it only works sometimes, and randomly. Any clue or ideas why?

game.ReplicatedStorage.StatsRemote.OnClientEvent:connect(function(wood,gold)

	local woodpercent = wood / maxwood.Value
	local woodpercentsize = woodpercent * 280
	local roundedwoodpercentsize = math.floor(woodpercentsize+.5)
		
	local goldpercent = gold / maxgold.Value
	local goldpercentsize = goldpercent * 280
	local roundedgoldpercentsize = math.floor(goldpercentsize+.5)
		
	script.Parent.WoodAmount:TweenSize(UDim2.new(0,roundedwoodpercentsize,0,40))
	script.Parent.GoldAmount:TweenSize(UDim2.new(0,roundedgoldpercentsize,0,40))

end)

thats not how you tween there is alot that goes into it but heres what you can use for now and a link to more info

Just copy/ paste link isn't working rn

Example:

 script.Parent.GoldAmount:TweenSize(UDim2.new(0,roundedgoldpercentsize,0), "In", "Linear",2, false)
