trigger updateEquipmentDeatilField on Equipment_in_Room__c (before insert, before update) {
    try {
        List<Equipment_Specification__c> EquipmentDetails = new List<Equipment_Specification__c>();
        For (Equipment_in_Room__c r: Trigger.New) {
            if (r.Hospital_Name__c.equalsIgnoreCase('Dartmouth General Hospital')) {
                EquipmentDetails = [Select id, Name, Equipment_in_Room__c from Equipment_Specification__c where id =: r.Plan_Id__c limit 1];
                for (Equipment_Specification__c es : EquipmentDetails ) {
                    if (es.Equipment_in_Room__c == null ) { 
                        es.Equipment_in_Room__c = 'DG,'  ;
                    } else if (es.Equipment_in_Room__c.indexOf('DG') == -1 ) {
                        es.Equipment_in_Room__c = es.Equipment_in_Room__c + 'DG,'  ;
             }
                    update EquipmentDetails;
                }
                
            } else if (r.Hospital_Name__c.equalsIgnoreCase('Halifax Infirmary')) {
                EquipmentDetails = [Select id, Name, Equipment_in_Room__c from Equipment_Specification__c where id =: r.Plan_Id__c limit 1];
                for (Equipment_Specification__c es : EquipmentDetails ) {
