code for save skin, what's wrong with this code

[synskidz]

I edit it from resource called "Freeroam".

There is a bookmark option for save player location but i want to change it to save player skin. What's wrong with my code. This is the client-side Lua

local bookmarkList
local bookmarks

function initBookmarks ()
	bookmarkList = wndBookmarks.controls[1].element
	if bookmarks then return end
	loadBookmarks ()
	addEventHandler("onClientGUIDoubleClick",bookmarkList,gotoBookmark)
end

function loadBookmarks ()
	bookmarks = {}
	local xml = xmlLoadFile("bookmarks.xml")
	if not xml then
		xml = xmlCreateFile("bookmarks.xml","catalog")
	end
	guiGridListClear(bookmarkList)
	for i,child in ipairs (xmlNodeGetChildren(xml) or {}) do
		local row = guiGridListAddRow(bookmarkList)
		guiGridListSetItemText(bookmarkList,row,1,tostring(xmlNodeGetAttribute(child,"name")),false,false)
		guiGridListSetItemText(bookmarkList,row,2,tostring(xmlNodeGetAttribute(child,"zone")),false,false)
		bookmarks[row+1] = {tonumber(xmlNodeGetAttribute(child,"x"))}
	end
end

function saveBookmarks ()
	if fileExists("bookmarks.xml") then
		fileDelete("bookmarks.xml")
	end
	local xml = xmlCreateFile("bookmarks.xml","catalog")
	for row=0,(guiGridListGetRowCount(bookmarkList)-1) do
		local child = xmlCreateChild(xml,"bookmark")
		xmlNodeSetAttribute(child,"name",guiGridListGetItemText(bookmarkList,row,1))
		xmlNodeSetAttribute(child,"zone",guiGridListGetItemText(bookmarkList,row,2))
		xmlNodeSetAttribute(child,"x",tostring(bookmarks[row+1][1]))
		--xmlNodeSetAttribute(child,"y",tostring(bookmarks[row+1][2]))
		--xmlNodeSetAttribute(child,"z",tostring(bookmarks[row+1][3]))
	end
	xmlSaveFile(xml)
	xmlUnloadFile(xml)
end

function saveLocation ()
	local name = getControlText(wndBookmarks,"bookmarkname")
	if name ~= "" then
		local x = getElementModel(g_Me)
		local zone = getZoneName(x,y,z,false)
		if x and y and z then
			local row = guiGridListAddRow(bookmarkList)
			guiGridListSetItemText(bookmarkList,row,1,name,false,false)
			guiGridListSetItemText(bookmarkList,row,2,zone,false,false)
			bookmarks[row+1] = {x}
			setControlText(wndBookmarks,"bookmarkname","")
			saveBookmarks()
		end
	else
		outputChatBox("Please enter a name for the bookmark")
	end
end

function deleteLocation ()
	local row,column = guiGridListGetSelectedItem(bookmarkList)
	if row and row ~= -1 then
		table.remove(bookmarks,row+1)
		guiGridListRemoveRow(bookmarkList,row)
		saveBookmarks()
	end
end

function gotoBookmark ()
	local row,column = guiGridListGetSelectedItem(bookmarkList)
	if row and row ~= -1 then
		fadeCamera(false)
		if isPedDead(g_Me) then
			setTimer(server.spawnMe,1000,1,unpack(bookmarks[row+1]))
		else
		setTimer(setElementModel,1000,1,g_Me,unpack(bookmarks[row+1]))
			--setElementModel(player, skin)
			--setTimer(setElementPosition,1000,1,g_Me,unpack(bookmarks[row+1]))
		end
		setTimer(function () fadeCamera(true) setCameraTarget(g_Me) end,2000,1)
	end
end
