Help auto give event like lineage II curse sword

[newsubzero]

i want to make NPC auto give but error like this

[Error]: script_rid2sd: fatal error ! player not attached!
[Debug]: Source (NPC): dmdmswd at prontera (0,0)
[Warning]: script:get_val: cannot access player variable 'domswd', defaulting to 0

this is idea :

- NPC random time every 7 day to player who online except in vending,

- if player not online or online that item will delete automatically before random player get that.

- if player die item will lost.

- player who have that item can kill by other player

- if other player kill that player who have that item, other player will have that item.

- item can't be taken off, after equipped.

help me what should i do with my script ?

prontera,0,0,0 script dmdmswd -1,{
OnInit:
OnClock0000:
set .DmdTime,rand(24);
OnMinute00:
if( gettime(3) == .DmdTime ){
set .DelayMin,rand(60);
sleep ( .DelayMin * 60000 * 7 );
while(1){
 query_sql "select account_id from 'char' where online = 1 order by rand() limit 1", .@onl;

 if( CheckVending() ){
  DetachRID();
