Mount Quest Problem

[JIntors 8]

Hello devs I have a problem with my mount quest system.

here is my quest:

quest ride_mystery_boxes begin
	state start begin
		function Ride( vnum, remain_time )
			ride_info = {
				[71124] = { 20114,	item.get_socket(2)*60,	apply.EXP_DOUBLE_BONUS,	20,	1,	false	},
				[71125] = { 20115,	item.get_socket(2)*60,	apply.ATTBONUS_MONSTER,	10,		20,	false	},
				[71126] = { 20116,	item.get_socket(2)*60,	apply.ATTBONUS_MONSTER, 10,	20,	false	},
				[71127] = { 20117,	item.get_socket(2)*60,	apply.ATTBONUS_MONSTER,	15,	20,	false	},
				[71128] = { 20118,	item.get_socket(2)*60,	apply.ATTBONUS_MONSTER,	20,	20,	false	},
				[71137] = { 20120,	item.get_socket(2)*60,	apply.MOV_SPEED, 0,	1,	false,	false,	false},
				[71138] = { 20121,	item.get_socket(2)*60,	apply.MOV_SPEED, 0,	1,	false,	false,	false},
				[71139] = { 20122,	item.get_socket(2)*60,	apply.MOV_SPEED, 0,	1,	false,	false,	false},
				[71140] = { 20123,	item.get_socket(2)*60,	apply.MOV_SPEED, 0,	1,	false,	false,	false},
				[71141] = { 20124,	item.get_socket(2)*60,	apply.MOV_SPEED, 0,	1,	false,	false,	false},
				[71142] = { 20125,	item.get_socket(2)*60,	apply.EXP_DOUBLE_BONUS, 50,	1,	false,	false,	false},
				}

			if pc.level < ride_info[vnum][5] then
				say("")
				say(gameforge.ride._010_say)
				say("")
			else
				if 112 == pc.get_map_index() then
					return
				end
				if ride_info[vnum][2] == 0 and remain_time != 0 then
					pc.mount( ride_info[vnum][1], remain_time*60 )
					pc.mount_bonus( ride_info[vnum][3], ride_info[vnum][4], remain_time*60 )
				else
					pc.mount( ride_info[vnum][1], ride_info[vnum][2] )
					pc.mount_bonus( ride_info[vnum][3], ride_info[vnum][4], ride_info[vnum][2] )
				end

				if true == ride_info[vnum][6] then
					pc.remove_item(vnum, 1)
				end	
			end	
		end

		when login begin
			local vnum, remain_time = pc.get_special_ride_vnum()
			if  vnum != 71124 and vnum != 71125 and vnum != 71126 and vnum != 71127 and vnum != 71128 and vnum != 71137 and vnum != 71138 and vnum !=71139 and vnum !=71140 and vnum !=71141 and vnum !=71142  then
				return
			end
			if 0 != vnum then
				ride_mystery_boxes.Ride(vnum, remain_time)
			end
		end

		when 71124.use or 71125.use or 71126.use or 71127.use or 71128.use or 71137.use or 71138.use or 71139.use or 71140.use  or 71141.use or 71142.use begin
			 if pc.is_polymorphed() then
				 say("")
				 say(gameforge.ride._020_say)
				 say("")
			elseif false == pc.is_riding() then
			 	if true == horse.is_summon() then
					horse.unsummon()
				end
				 ride_mystery_boxes.Ride(item.vnum, 0)
			 else
				say("")
				 say(gameforge.ride._030_say)
				 say("")
			 end
		end
	end
end
