This suggests that oppStages is null - I'd add some debug to dump out the setting once you've retrieved it.

The only reason I see is 'oppStages' object being nul and not being instantiated correctly in the 3 line in the script. Can you add a system.debug to check the value of oppStages?

yes oppstages is null ...but I am not sure why?

Have a look at what what Stage_And_Status__c.getInstance('Opportunity Stages') does. It surely returns an instance of Stage_And_Status__c class but there may be a spelling issue with the parameter passed or it not being able to understand the term 'Opportunity Stages'

On second thoughts this looks like the code trying to get a custom setting. Have you setup a list custom setting with the name 'Opportunity Stages'. If yes, is the name correct?
