.lua frame not appearing

[Sythalin]

Used to XML, trying to get the hang of doing it all .lua

function CFM_CreateConfig()
	-- Create config frame
	local f = CreateFrame("Frame", "CFM_Config", UIParent)
	f:SetWidth(100)
	f:SetHeight(100)
	f:SetPoint("Center")
	f:SetBackdrop({
		bgFile = "Interface\DialogFrame\UI-DialogBox-Background",
		edgeFile = "Interface\DialogFrame\UI-DialogBox-Border",
		tile = "true",
		tileSize = 32,
		edgeSize = 32,
		insets = {left = 11, right = 12, top = 12, bottom = 11}
		})
	f:SetBackdropColor(0,0,0,1)
end

Results in no frame, either mod called or /script called.
