Help with Warning

[harib]

I need help with Warning:

435: Bad argument @ 'setElementID' [Expected element at argument 1, got nil]

437: Bad argument @ 'destroyElement' [Expected element at argument 1, got nil]

    elseif currentWeaponID == weapID1 then 
        setElementID(player, "elementWeaponBack[source]") -- PRUEBA ELIMINAR ERROR 
        detachElementFromBone(elementWeaponBack[source]) 
        destroyElement(elementWeaponBack[source]) -- PRUEBA ELIMINAR ERROR 
        elementWeaponBack[source] = false 
      end 

FUCTION COMPLETE:

      
    function weaponSwitchBack(previousWeaponID, currentWeaponID) 
      local weapon1 = getElementData(source, "currentweapon_1") 
      if not weapon1 then 
        return 
      end 
      local ammoData1, weapID1 = getWeaponAmmoType(weapon1) 
      local x, y, z = getElementPosition(source) 
      local rx, ry, rz = getElementRotation(source) 
      if previousWeaponID == weapID1 then 
        if elementWeaponBack[source] then 
          setElementID(player, "elementWeaponBack[source]") 
          detachElementFromBone(elementWeaponBack[source]) 
          destroyElement(elementWeaponBack[source]) 
          elementWeaponBack[source] = false 
        end 
        elementWeaponBack[source] = createObject(getWeaponObjectID(weapID1), x, y, z) 
        setObjectScale(elementWeaponBack[source], 0.875) 
        if elementBackpack[source] then 
          attachElementToBone(elementWeaponBack[source], source, 3, 0.19, -0.31, -0.1, 0, 270, -90) 
        else 
          attachElementToBone(elementWeaponBack[source], source, 3, 0.19, -0.11, -0.1, 0, 270, 10) 
        end 
      elseif currentWeaponID == weapID1 then 
        setElementID(player, "elementWeaponBack[source]") -- ESTA ES LA 435 
        detachElementFromBone(elementWeaponBack[source]) 
        destroyElement(elementWeaponBack[source]) -- ESTA ES LA 437 
        elementWeaponBack[source] = false 
      end 
    end

Change "player" to source, and remove the quotes from elementWeaponBack[source].

[harib]

Do not quite understand ... So?

    elseif currentWeaponID == weapID1 then 
    setElementID(source, elementWeaponBack[source]) -- PRUEBA ELIMINAR ERROR 
        detachElementFromBone(elementWeaponBack[source]) 
        destroyElement(elementWeaponBack[source]) -- PRUEBA ELIMINAR ERROR 
        elementWeaponBack[source] = false 
      end 

And this error of the other line? How do I fix it

437: Bad argument @ 'destroyElement' [Expected element at argument 1, got nil]

[Castillo]

Means it attempted to destroy an element which doesn't exist.

[harib]

Then put the code that I put up already should not given Warning not?

The code I wrote is OK?

Thanks

[Castillo]

Add a check to see if the element exists, use

isElement 

[harib]

He has told me many things and I do not understand very well, it could if it is not very difficult to explain it to me with the code? I'm learning but it is very complicated.

I feel the inconvenience and thank you for your help

[harib]

Help please

[Castillo]

if isElement ( elementWeaponBack [ source ] ) then 
    destroyElement ( elementWeaponBack [ source ] ) 
end 

[harib]

Like this? should work?

elseif currentWeaponID == weapID1 then 
    setElementID(source, elementWeaponBack[source]) -- PRUEBA ELIMINAR ERROR 
    detachElementFromBone(elementWeaponBack[source]) 
    if isElement ( elementWeaponBack [ source ] ) then 
    destroyElement ( elementWeaponBack [ source ] ) 
    end 
    elementWeaponBack[source] = false 
    end 

[Castillo]

Yes, that's what I meant.
