Now i Got...
trigger TesTRollUP on Store__c (after insert,after update) {
set<ID> sid = new set<ID>();
list<NewSpace__Shopper__c> ns= new list<NewSpace__Shopper__c>();
Integer tot =0;
for(NewSpace__Store__c s : [select id ,NewSpace__Shopper__c,NewSpace__Marks__c from NewSpace__Store__c where id in : Trigger.newMap.keySet() ])
{
sid.add(s.NewSpace__Shopper__c);
}
for(NewSpace__Store__c ss : [select id,NewSpace__Marks__c from NewSpace__Store__c where NewSpace__Shopper__c IN : sid ])
{
tot+=Integer.valueof(ss.NewSpace__Marks__c);
}
for(NewSpace__Shopper__c nss:[select id,NewSpace__Total_Store_Marks__c from NewSpace__Shopper__c where id in:sid ])
{
nss.NewSpace__Total_Store_Marks__c =tot;
ns.add(nss);
}
update ns;
}
