Replace this line in code:

 

Map_Types.put(AR1.Type__c,AR1.Type__c);

 

with this one and I am sure it will fix the problem.

 

Map_Types.put(AR1.Type__c,AR1);

Your map declaration:

public Map<string,String> Map_Types=new Map<string,String>();

 

You put values in map:

Map_Types.put(AR1.Type__c,AR1.Type__c);

 

Access value from map:

Map_Types.get(a2.Type).Running_Number__c;

 

 

Map type is String, String which means key is string value is string. While you put value in map you put string as key and value.

 

While accessing data from map you are accessing map value as object: object.property. Either put wrong value in map or you are accessing it incorrectly. It dependes on what exactly you want to do.

I have Two objects 

 

1) Account

2) runningNumber

 

They both are not related, But they got same field names as "TYPE"

 

From running i need number field value with same type of acct, and then update the one of the field in Account.
