Hi,  

I installed the Birthday Reminder app from the Appexchange store. The code is unmanaged and I was trying to change the field from which the code is pulling the email address from for the recipient. I tried a couple of different ways, but none of them worked. Please help. Here is the code:

global class BirthdayCronJob implements Schedulable{ 
	
		global void execute(SchedulableContext SC) {
      		    sendmail(); 
                }
		
		public List<Id> getBirthdayEmailAddresses(Integer Month, Integer Day) 
     	{ 
        	List<Id> mailToIds = new List<Id>();
        	 
        	
	        Contact[] c = [SELECT Id, email, Birthdate, Send_Birthday_Email__c, HasOptedOutOfEmail
	        				FROM Contact 
	        				WHERE DAY_IN_MONTH(Birthdate) = : Day 
						AND CALENDAR_MONTH(Birthdate) = : Month   
	        				];
        
			       
    	    for(Contact recipient : c) {
    	    		    	    		
    	    		if (recipient.Send_Birthday_Email__c == true && recipient.HasOptedOutOfEmail == false)
    	    		{
    	    			mailToIds.add(recipient.Id);	
    	    			System.Debug('\n*******Recipient: '+ recipient.email);
    	    			 
    	    		} else {
    	    			
    	    			System.Debug('\n*******NO Recipient');
    	    		}
	        	
        	}
        	return mailToIds;
     	}
        public void sendMail() 
    	{
		String debugAddress = 'eyewell@salesforce.com';
		String BirthdayEmailTemplateName = 'Happy_Birthday';
		String AnniversaryEmailTemplateName = 'Celebrating_your_Anniversary';			
		String debugMessage;
        	String[] toAddresses;

    		Integer DayOfEvent   = date.today().day();
			Integer MonthOfEvent = date.today().month();
 
        	List<Id> BirthdayIdsList = getBirthdayEmailAddresses(MonthOfEvent,DayOfEvent);

        	EmailTemplate birthdayTemplate = [select Id,Name,Subject,body from EmailTemplate where DeveloperName = :BirthdayEmailTemplateName];
		
        	if(birthdayTemplate != null && BirthdayIdsList.isEmpty() == false)
        	{

           		Messaging.MassEmailMessage birthdayMail = new Messaging.MassEmailMessage();
    
            	birthdayMail.setTargetObjectIds(BirthdayIdsList);
            	birthdayMail.setTemplateId(birthdayTemplate.Id);
            	birthdayMail.setUseSignature(false);
            	birthdayMail.setSaveAsActivity(true);

            	try {
            		Messaging.sendEmail(new Messaging.MassEmailMessage[] { birthdayMail });
            	}catch(Exception e)
            	{
            		System.Debug(e);
            	}
           
        	}
        	else
        	{
            	        System.Debug('BirthdayCronJob:sendMail(): Either an email template could not be found, or no Contact has a birthday today');
        	}


}

 So instead of the native Force.com Email field, I want to use a custom email field called "Secondary Email." I tried changing the SOQL statement, but it still didnt work.
