        if qb == 0 then		-- if the source player is NOT invisible
		qb  = 1		-- set qb to say the source player is invisible
		setElementAlpha ( source, 0 )	-- set the players alpha to 0 (make them invisible)
	else			-- else, if the source player IS visible
		qb = 0		-- set qb to say the source player is visible.
		setElementAlpha ( source, 255 )	-- set the players alpha to 255 (make them 100% visible)
