Script unable to access object?

I am using Roblox Studio to test. The script is server-side (global).

The code I have is here:

function text(text, color, time_)
	workspace.TextValues.Texts = text
	workspace.TextValues.Color = color
	workspace.TextValues.Time = time_
	workspace.TextValues.Change:Fire()
end
function difnumtotext(num)
	if num == 0 then
		return "Easy"
	elseif num == 1 then
		return "Medium"
	elseif num == 2 then
		return "Hard"
	end
end

function difnumtocolor(num)
	if num == 0 then
		return Color3.fromRGB(0, 255, 0)
	elseif num == 1 then
		return Color3.fromRGB(255, 255, 0)
	elseif num == 2 then
		return Color3.fromRGB(255, 0, 0)
	end
end
--Some other code that does not relate goes here
function choosemap()
	local mapnumber = math.random(1,#game.ServerStorage:GetChildren())
	if mapnumber == 1 then
		local clone = startgame(game.ServerStorage.Map1)
		text(workspace.MapValues.Names.Value .. "[" .. difnumtotext(workspace.MapValues.Difficulty.Value) .. "] by " .. workspace.MapValues.Creator.Value, difnumtocolor(workspace.MapValues.Difficulty.Value), 5)
elseif mapnumber == 2 then
	local clone = startgame(game.ServerStorage.Map2)
	text(workspace.MapValues.Names.Value .. "[" .. difnumtotext(workspace.MapValues.Difficulty.Value) .. "] by " .. workspace.MapValues.Creator.Value, difnumtocolor(workspace.MapValues.Difficulty.Value), 5)
elseif mapnumber == 3 then
	local clone = startgame(game.ServerStorage.Map3)
	text(workspace.MapValues.Names.Value .. "[" .. difnumtotext(workspace.MapValues.Difficulty.Value) .. "] by " .. workspace.MapValues.Creator.Value, difnumtocolor(workspace.MapValues.Difficulty.Value), 5)
	end
end

I want to make it so the values in the folder (TextValues) change. Instead, I get the following error:

16:40:53.189 - Texts is not a valid member of Folder 16:40:53.190 - Stack Begin 16:40:53.190 - Script 'Workspace.GameScript', Line 10 - global text 16:40:53.191 - Script 'Workspace.GameScript', Line 53 - global choosemap 16:40:53.191 - Script 'Workspace.GameScript', Line 60 16:40:53.192 - Stack End

I know what it is saying but it doesn't make sense. I can see the folder and values existing right here:

Can someone please help me fix this? Thanks!
