Hi,

I want to send email when a field is updated in a custom object. so i have a trigger written. i also created a email template.

I find that the targetobjectid is a required field while sending an email. Its erroring out where i am setting targeto

bject .Id. It says Save error: Variable does not exist: Lstuser.id

Any ideas what am i doing wrong

trigger change_action on Ticket__c (after update) {
	//List<user>Lstuser= new List<user>();
	List<id> lstid=new List<id>();
	List<string> lstemail= new List<string>();
	Map<id,string> Mapemail = new Map<id,string>();
	

	for(ticket__c t:trigger.new)
	{
		if(trigger.isUpdate)
		{
			if(t.Actions__c!=System.Trigger.oldMap.get(t.Id).Actions__c)
			{
				lstemail.clear();
				lstemail.add(t.Initiator_Email__c);
				lstemail.add(t.Admin_email__c);
				
				for(User Lstuser:[select id, email,username from user where email in :lstemail]);
				{
				List<EmailTemplate> emailtemplatelist = new List<EmailTemplate>();
				emailtemplatelist=[select id, name from EmailTemplate where name='Update on ticket'];
				if (emailtemplatelist.size()>0)
				{
					//emailtemplatelist[0]
					Messaging.SingleEmailMessage mail = new Messaging.SingleEmailMessage();
					mail.toAddresses = new string[]{t.Initiator_Email__c,t.Admin_email__c};
					//mail.setToAddresses(t.Initiator_Email__c);
					mail.setTemplateId(emailtemplatelist[0].id);
/**************************Its THROWING ERROR ON BELOW LINE **********************************/		 
					mail.TargetObjectId(Lstuser.id);//ERROR ON THIS LINE
					Messaging.sendEmail(new Messaging.SingleEmailMessage[] { mail });
				}
			}
			}
		}
	}

}
