Can I ask for help with this code?

[PeterP]

function addCapacete (source)
    local capacete1 = getElementData(source, "capaceteOn")
    if capacete1 then
        exports.pAttach:detach(capacete1)
        destroyElement(capacete1)
        setElementData(source, "capaceteOn", nil)
    else
        capacete1 = createObject(1873,0,0,0)
        setElementData(source, "capaceteOn", capacete1)
        exports.pAttach:attach(capacete1, source, 8, -0.02,0,0,0,0,-104.4)
    end
end
addEvent ( "onaddCapacete", true )
addEventHandler("onaddCapacete", getRootElement(), addCapacete)

I'm getting an error: bad argument @  'destroyElement'  [expected element at argument 1] on line 5

why am I getting this error?

destroyElement for elements,If you want to delete element data, use removeElementData on server side

But I'm trying to destroy the object that was once attached to the player,

if capacete1 then

This checks whether a value is assigned to capacete1 (this value could be anything -- a string, number, userdata, coroutine, element, etc.), not whether it is a valid value for the purposes of your script.

If the warning message you get says "expected element", it means you've passed it something that isn't an element (for instance, it could be a userdata reference to an element that's been destroyed by another script). A solution that gets rid of the warning is

if isElement(capacete1) then
