The trigger below runs through a set of logic looking for matching Contacts/Person Accounts based on email address and creating Accounts/Contacts and Person Accounts where they don't already exist.

Everything is working fine except for the bit that is highlighted.

It is supposed to create a new Person Account and then update a lookup with the new Person Account ID.

The Person Account record is being created just fine, but the lookup is not being populated like it is with the rest of the trigger.

If a second record is created with a matching email address, the lookup is populated on the second record as it should.

Any idea what I am doing wrong??

Thanks is advance for any help.

trigger enquiryTrigger on Enquiry__c (before insert) {

// Get the email address from the enquiry record
   List<Enquiry__c> enqEmail = [select email__c from Enquiry__c where ID in :Trigger.new];
 
   for(Enquiry__c e: Trigger.new){

// Get the contact with matching email address   	
      List<Contact> conID = [select Name from Contact where Email = :e.email__c limit 1];

// If matching contact is found update Enquiry record      
      if (conID.size() > 0) {
      	e.Matching_Contact__c = conID[0].Id;

      } 

//If no matching contact is found and enquiry DOES NOT contain a Company, create a Person Account

else if (e.company__c == null) {

		Account pa = new Account (RecordTypeId = '01220000000DpJM', LastName = e.Name, PersonEmail = e.Email__c, Phone = e.Phone__c);
		insert pa;
		
		// Update Enquiry with new Person Account      		
		e.Matching_Contact__c = pa.PersonContactId;
      	
       } else {

		// If Enquiry does contain a Company check for matching Account record       	
		       	List<Account> accName = [select Id from Account where Name = :e.Company__c limit 1];
		      
		      	if (accName.size() > 0) {
		
				// If matching Account record is found, create a contact on the existing Account
				      		Contact c = new Contact (LastName = e.Name, Phone = e.Phone__c, Email = e.email__c, AccountId = accName[0].Id);
					       	insert c;
				
				// Update Enquiry with new Contact	       	
					       	e.Matching_Contact__c = c.Id;
	       	
		      	} else {
		      		
				// If no matching Account is found, create an Account        		
					       	Account a = new Account (Name=e.Company__c);
					       	insert a;
					       	
				// Create a related Contact	       	
					       	Contact c = new Contact (LastName = e.Name, Phone = e.Phone__c, Email = e.email__c, AccountId = a.Id);
					       	insert c;

					       	e.Matching_Contact__c = c.Id;
