Hi,
 I am writting trigger in I have Stakeholder object that is the related list to Opportunity and Contact. On Contact detail page, we have NPS ID field on the Contact detail page that is look up to the Voice of NPS object (Customer Object). The following code will get the NPS ID field value from the Contact detail page in the Stackholders page which we can able to clickable.
Create NPS Id 1 field on the stackholders object which is the look up to the Voice of NPS object (Customer Object)

This is my trigger

trigger updateNpsid on shareholder__c (before insert,before update) {
List<id> ConList = new List<id>();
 for(shareholder__c sh:Trigger.New){
ConList.add(sh.Contact_Name__c);
 }
 List<Contact> lc = [Select NPS_Id__c,NPSlookup__c From Contact Where id IN : ConList];
 for(shareholder__c sh:Trigger.New){
 sh.NPS_Id1__c = lc.NPS_Id__c;
 }
}

Error is Variable does not exist: NPS_Id__c
Alredy i am create the field in contact 

I do not understand which list variable assigned the values were I am missing it's my code
global class SAPRequest{

WebService static void SendApprovalRequest(string id) {


// create the new approval request to submit
Approval.ProcessSubmitRequest req = new Approval.ProcessSubmitRequest();
req.setComments('Submitted for approval. Please approve.');
 req.setObjectId(id);
 req.setNextApproverIds(Id[]);
// submit the approval request for processing
Approval.ProcessResult result = Approval.Process(req);


// display if the reqeust was successful
System.debug('Submitted for approval successfully: '+result.isSuccess());
}
}
Error is showing Error: Compile Error: Missing ')' at '[' at line 10 column 27

Hi,
 I am writting trigger in I have Stakeholder object that is the related list to Opportunity and Contact. On Contact detail page, we have NPS ID field on the Contact detail page that is look up to the Voice of NPS object (Customer Object). The following code will get the NPS ID field value from the Contact detail page in the Stackholders page which we can able to clickable.
Create NPS Id 1 field on the stackholders object which is the look up to the Voice of NPS object (Customer Object)

This is my trigger

trigger updateNpsid on shareholder__c (before insert,before update) {
List<id> ConList = new List<id>();
 for(shareholder__c sh:Trigger.New){
ConList.add(sh.Contact_Name__c);
 }
 List<Contact> lc = [Select NPS_Id__c,NPSlookup__c From Contact Where id IN : ConList];
 for(shareholder__c sh:Trigger.New){
 sh.NPS_Id1__c = lc.NPS_Id__c;
 }
}

Error is Variable does not exist: NPS_Id__c
Alredy i am create the field in contact 

I do not understand which list variable assigned the values were I am missing it's my code
global class SAPRequest{

WebService static void SendApprovalRequest(string id) {


// create the new approval request to submit
Approval.ProcessSubmitRequest req = new Approval.ProcessSubmitRequest();
req.setComments('Submitted for approval. Please approve.');
 req.setObjectId(id);
 req.setNextApproverIds(Id[]);
// submit the approval request for processing
Approval.ProcessResult result = Approval.Process(req);


// display if the reqeust was successful
System.debug('Submitted for approval successfully: '+result.isSuccess());
}
