Alchamy quest

[HattanBinNassar 4]

hey ! ,, i made this quest :
 

quest dragon_soul_activation begin
    state start begin
		when levelup or letter with pc.level >= 30 begin
			send_letter(gameforge.dragon_soul._1010_sendLetter)
			local v = find_npc_by_vnum(20001)
			
			if 0 != v then
				target.vid("__TARGET__", v, mob_name(20001))
			end
		end
	
        when 20001.chat." ÊÝÚíá ÇáßíãÇÆí " begin
			target.delete("__TARGET__")
            say(" Êã ÇáÊÝÚíá ")
			ds.give_qualification()
            char_log(pc.get_player_id(), 'DS_QUALIFICATION', 'SUCCESS')
        end
    end
end

for the ds.give_qualification() to be active on level 30 , the problem is ( the quset never end even when you have the - ds.give_qualification() - and already talk to the npc and keep reload when you login or change char )
