The code that is coming out false reads: if(maprtID_rtName.get(escalatedcase.id) == 'NationalClientService') {

for some reason, it comes out false... not sure why, but i tried to debug it by pritning out the value for maprtID_rtName.get(escalatedcase.id)) and it errors saying that it is printing nulls.

here's my record type: 

Record Type Label	National Client Service	Active	
Support Process	National Client Service	 	 
Record Type Name	NationalClientService

CODE BELOW:

trigger EscalateCase on Case (before update) {
  List<RecordType> rTypes = [select id,name from RecordType where SobjectType='Case'];    //pull recordtype Id's and record type names from recordtypes where the sobject is contract
 	
  MAP<Id , String> maprtID_rtName = new MAP<ID , String>();  //map record type ID's to record type names.
  for(RecordType rTypeObj :  rTypes)
  {
  	maprtID_rtName.put(rTypeObj.id , rTypeObj.Name); //for all recordtypes... log id's and record type names.
  }
  
  List<RecordType> rTypesCases = [select name,id from RecordType where SobjectType='Case'];    //pull recordtype Id's and record type names from recordtypes where the sobject is contract
  
  MAP<String, ID> maprtName_rtIDCases = new MAP<String, ID>();  //map record type ID's to record type names.
  for(RecordType rTypeObj :  rTypesCases)
  {
  	maprtName_rtIDCases.put(rTypeObj.Name, rTypeObj.id); //for all recordtypes... log id's and record type names.
  }


List<Case> Cases = new List<Case>();
for (Case escalatedcase:Trigger.new){

//trying to close the parent case while children are still open	
if (escalatedcase.Status=='Closed') { //trying to close the parent case while children are still open
	integer close = [Select count() from Case where ParentId = :escalatedcase.id and isClosed != true];
	if (close > 0) {
		escalatedcase.addError('There are still Child Cases Open - Please close and try again!');
	}
}
//END trying to close the parent case while children are still open


	if(maprtID_rtName.get(escalatedcase.id) == 'NationalClientService') { // This is the IF statement that is failing.
		if (escalatedcase.Escalate_to__c == 'Tier 2 - Internal Support') {
			if(escalatedcase.Tier_2_Escalation_Level__c == 'Billing Resolution') {
				if (escalatedcase.IsEscalated==false) {
					if(escalatedcase.ParentId == null) {
						Case CaseAdd = escalatedcase.clone(false, true);
						CaseAdd.RecordTypeId = maprtName_rtIDCases.get('Billing Resolution');
						CaseAdd.ParentId = escalatedcase.id;
						Cases.add(CaseAdd);
						escalatedcase.Status = 'Escalated to Tier 2';
						escalatedcase.IsEscalated = true;
					} else {

							CaseAdd.Status = 'Completed';
							CaseAdd.IsEscalated = false;
							Cases.add(CaseAdd);
						}
						
					}
				}
			}
		}
	} else {
		escalatedcase.addError('test');
		escalatedcase.addError(maprtID_rtName.get(escalatedcase.id)); ///It's throwing the error down here... because the if statement from above is false
	}
