Code:

function moveRucksakOutOfInventory (itemName) 
    local sack = getElementData ( source, "rucksak" ) 
    if sack and sack[1] ~= 0 then 
        local x,y,z = getElementPosition(source) 
        local item,itemString = getItemTablePosition(itemName) 
        local itemPickup = createItemPickup(item,x+math.random(-1.25,1.25),y+math.random(-1.25,1.25),z,itemString,sack) 
        if elementBackpack[source] then 
            detachElementFromBone(elementBackpack[source]) 
            destroyElement(elementBackpack[source]) 
        end 
        setElementData ( source, "rucksak", { 0 } ) 
    end 
end 

Error: attempt to index global 'elementBackpack' (a nil value) (Error line: if elementBackpack[source] then)

Perhaps try being a bit friendlier to those who are people on the forum, @A Concerned Citizen

Because I see all your replies and they all say the same, 'go to the wiki we don't help you'.

If Sasu wants to help someone he can do that, that's polite. If you don't want/can't help then don't reply pls.

Anyway keep on the good work Sasu, I remember you from waaaay back on the forum.

There are too many of those stupid kids posting parts from DayZ/etc. gamemode, when they have no fu idea how to write a single line of code.

It is shameful, disrespectful and against the forum rules.

There are hardly any seriously posts.

Citizen spoke the hard truth, sometimes that relieves.

He didn't flame, just gave his opinion.

The main reason why they created forums is for discussing problems. This is a problem, so we can discus it and give our opinion.

It is a good thing to save Sasu from wasting time, he can play mta/(or help somebody else) instead of trying to help somebody who can't be helped. I would be glad if somebody did that for me.
