Attempt to call table value when not calling a table value?

script.Parent.Triggered:Connect(function(player) local character = player.Character

if player.leaderstats.Rebirths.Value >= script.Parent.Parent.Parent.Price.Value then
	script.Disabled = true
	script.Parent.Enabled = false
	player.PlayerGui.PortalFX.TextLabel.Visible = true
	player.PlayerGui.PortalFX.Circle:TweenSize(UDim2(0, 0,2.5, 0))
	wait(1)
	character.Head.CFrame = CFrame.new(game.Workspace:WaitForChild("50 Rebirths").Position)
	wait(1)
	player.PlayerGui.PortalFX.Circle:TweenSize(UDim2.new(1.5, 0,2.5, 0))
	script.Disabled = false
	script.Parent.Enabled = true
	player.PlayerGui.PortalFX.TextLabel.Visible = true
end

end)

Its giving me an error for this line: "player.PlayerGui.PortalFX.Circle:TweenSize(UDim2(0, 0,2.5, 0))" Saying that its attempting to call a table value

I am not trying to make a table value, I was just trying to follow a tutorial for a portal teleporting system.

TweenService takes a table for the parameters and gets the matching properties for it. I believe it should be fixed if you try this?

local size = {}
size.Size = Udim2.new(1.5,0,2.5,0)
player.PlayerGui.PortalFX.Circle:TweenSize(size)

Let me know if this worked.
