How to save/load in this specific way?

I want to make a script.. But I need to make the savefile stuff first, right? Soo.. I tried to, after looking at some other related stuff, and putting it together to make the save system I want... But I have no idea what I'm doing

So I want it like this: Theres current level, exp, and next level for each stat, and they are next to each other in the savefile, like this

4 8047 10000

Thats level 4 with 8047 exp and the next level is 10000 exp, for the health stat. The next line should be the regen stat, and then some other stats.

4 8047 10000
2 29245 100000
5 59 100
7 74 100
9 653 1000
3 12 100

What I currently have as script is this:

Spoiler

The first bit.. I think it's supposed to give new players those stats, and the loading bit (which is missing) should give players with a savegame the saved stats.

The second bit is obviously for saving stats... Dunno if I did that right.

What do I have to do to make this work?

Why don't you just save a serialized table string into the file and just load ALL the data you need?

It's basically when you turn a table into a string (using serialization function, end result is going to be sth like "{exp = 5, level = 2}") then save it and just load using dofile or loadstring commands. It's much more dynamic and you won't have to fuck with whole saving system just because player table gained a few extra variables.

But I think it's too complicated for you, sorry for wasting your time.

I tried something with a table and got this:
LUA ERROR: sys/lua/Accu_server.lua:21: attempt to index global 'Stats' (a nil value)

Heres the code

Spoiler

EDIT: Changed a bit, and now uhh.. I got a save, but it only says "Stats".

table.uneval (6) or file

[DEV] Table Serialization 1.3 (3)
You feed this serialize() function a table and get a string returned which can be written to a file. Then you only need to execute the file (dofile("example")) and you'll get your table loaded

With

table.uneval (6), you can save and load this way(assume that the data variable name is Stats)

dofile"sys/lua/table_uneval.txt"
Stats={}

-- load
addhook("join","_join")
function _join(id)
	local f=io.open("sys/lua/Accu_server_saves/"..player(id,"usgn")..".sav","r")
	if f==nil then return end
	local s=loadstring("return "..f:read("*a"))
	Stats[id]=s()
	f:close()
end

-- save
addhook("leave","_leave")
function _leave(id)
	if player(id,"usgn")>0 then
		local f=io.open("sys/lua/Accu_server_saves/"..player(id,"usgn")..".sav","w")
		f:write(table.uneval(Stats[id]))
		f:close()
	end
end

-- if you want to save at other than leave(like save every minute), just call _leave(id) where id=player id. example
-- _leave(1)	-- save data for player with id 1
