DetachElement from Player

[redditing]

function building(source, command, detached)
	xP, yP, zP = getElementPosition(source)
	
	local build = createObject(3374, xP, yP, zP)
	
	attachElements(build, source, 0, 3, 1)
	
	setElementAlpha(build, 150)
	
	if detached=="detach" then
		setElementAlpha(build, 255)
		if isElement(build) then
			detachElement(build)
		end
	end
end

addCommandHandler("setBuild", building)

When I type the command, a block of hay appears in front of me, but when I type the command with "detach" then I get an error. Can anything be done about it?

You have misspelled detachElements, you typed detachElement without s.

Does this solve your problem?
