HI all, 

can any body help me in the following code.

I am new to apex code..

trigger EventComplete_Opportunity on Event (after insert,after update) {

Map <Id, String> OppStatus = new Map <Id, String>();
Map <Id, String> OppStatusS = new Map <Id, String>();
List <Opportunity> OppToUpdate = new List <Opportunity>();
List <Opportunity> OppToUpdateS = new List <Opportunity>();
set<ID> OPPTaskIDS = new set<ID>();
String Last_Activity;
Date Last_Activity_Date;
String Next_Step;
Date Next_Step_Date;
DateTime ComEndDtae=datetime.now() ;

for(Event e : trigger.new) {
if(e.whoId != null) {
String x = e.whoId;
// 006 is a Opportunity
if (x.substring(0,3) == '006' ){
OppStatus.put(e.whoId,e.Subject);
Last_Activity = e.Subject;
Last_Activity_Date = date.today();
}
}

for(Opportunity o : [Select id, Last_Activity__c, Last_Activity_Date__c from Opportunity where id in :OppStatus.keyset()]) {
o.Last_Activity__c = Last_Activity;
o.Last_Activity_Date__c = Last_Activity_Date;
OppToUpdate.add(o);
}

if(OppToUpdate.size() > 0)
update OppToUpdate;
OppToUpdate.clear();


if(e.whatid<>null){
OPPTaskIDS.add(e.whoId);
}


if(OPPTaskIDS.size()>0){

for(Opportunity o: [Select o.Id, o.Next_Step__c, o.Next_Step_Due_Date__c,
(Select Id, Subject,ActivityDate From Events ORDER BY StartDateTime ASC)
From Opportunity o where Id in :OPPTaskIDS]){

o.Next_Step__c = o.Events[0].Subject;
o.Next_Step_Due_Date__c = o.Events[0].ActivityDate;
OppToUpdateS.add(o);
}
}

if(OppToUpdateS.size() > 0)
update OppToUpdateS;
OppToUpdateS.clear();

}
}

But after completion of Events based on date..still it is showing as Next Activity and Next activity Due date..

Please help me out from this...

Thanks in Advance!!!
