i think i still doesnt know where to put "end" and "return"
whats wrong with this script?

function onUse(cid, item, fromPosition, itemEx, toPosition)
    local container = 0
    local cost = 20000
    local potion_id = 2273
    local backpack_id = 2000
    if item.uid == 10203 and item.itemid == 1740 then
            container = doPlayerAddItem(cid, backpack_id, 1)
            for i = 1, 20 do
                doAddContainerItem(container, potion_id, 2268, 2294)
            end
return TRUE
end

i get a "end" error

it would be good if you could fix so you can buy promotion instead of having it when you start

You forgot the ending "end" which declares the function to be ended now.

If you start a function you have to end the function aswell.

example:

function youHaveToCloseThis(cid)
-- code
end -- this end belongs to the function "youHaveToCloseThis(cid)"

function youHaveToCloseThis(cid)
     if blablabla(cid) then
          -- code
     end -- this end belongs to the previous "if"
end -- this end belongs to the function "youHaveToCloseThis(cid)"

function onUse(cid, item, fromPosition, itemEx, toPosition)
    local container = 0
    local cost = 20000
    local potion_id = 2273
    local backpack_id = 2000
    if item.uid == 10203 and item.itemid == 1740 then
            container = doPlayerAddItem(cid, backpack_id, 1)
            for i = 1, 20 do
                doAddContainerItem(container, potion_id, 2268, 2294)
            end
    end
    return TRUE
end

I hope that you can understand it now

can you explain why it is 3 "end"? its only 1 "if" and one function.

and can you edit the script so its like a quest, you can only do it 1 time.

and when im rightclicking on the chest i get a backpack but no runes inside.. i get a error:

[08/07/2009  02:29:00] Lua Script Error: [Action Interface] 
[08/07/2009  02:29:00] data/actions/scripts/own made/bprunor.lua:onUse

[08/07/2009  02:29:00] luaDoAddContainerItem(). Container not found

Thank you for helping me.

It's a good tutorial, even tho i'm good at lua already

 

[Evil Hero]

sorry TriWear, didn't saw your post lately.

try this:

  function onUse(cid, item, fromPosition, itemEx, toPosition)
    local container = 0
    local cost = 20000
    local potion_id = 2273
    local backpack_id = 2000
    if item.uid == 10203 and item.itemid == 1740 then
            container = doPlayerAddItemEx(cid, backpack_id, 1)
            for i = 1, 20 do
                doAddContainerItem(container, potion_id, 2268, 2294)
            end
    end
    return TRUE
end
