Hi all,

           I am getting error on product insertion on Opportunity.apex class Update_OpportunityStageAndStatus_Class in which if you see line number 186,187 you will find getStage(lowest) having null value.The class file is too long,so

 i am sending it in two post.So please combine these two section into one and solve my problem

FIRST SECTION:
