Why is my Frame not appearing when I press the keybind that it's attached to?

Explanation

My goal is to simply have the frame open when I hit the keybind which is determined by a Value already set.

Issue

My issue is that no matter what I do, the frame will NOT become visible. I know that everything else works because the Tween control works perfectly fine.

Solutions

I've tried the following; Reprogramming everything from scratch x2; Removing variables; Adding & removing certain if statements; Adding print statements, everything runs for some reason.

Script Info

This is all in a local script.

Issue Code

local function AlternativeTabControl(GUIName)
	local Panel = script.Parent.Parent.Parent["Settings Frame"]
	local GUIs = script.Parent.Parent.Parent.GUIs
	for c,Frame in pairs (script.Parent.GUIScrollingFrame:GetChildren()) do
		for _,Button in pairs (Frame:GetChildren()) do
			if Panel.Position == UDim2.new(0.001, 0, Panel.Position.Y.Scale, 0) then
				if GUIs[GUIName].Visible == false then
					GUIs[GUIName].Visible = true
					if Frame.Name == GUIName.." Frame" then
						Button.Indicator.BackgroundColor3 = Color3.fromRGB(0,170,0)
						Button.Text = Button.LabelName.Value..": Open"
					end
				elseif GUIs[GUIName].Visible == true then
					GUIs[GUIName].Visible = false
					if Frame.Name == GUIName.." Frame" then
						Button.Indicator.BackgroundColor3 = Color3.fromRGB(170,0,0)
						Button.Text = Button.LabelName.Value..": Closed"
					end
				end
			end
		end
	end
end
