String aid{get;set;}

list<quote__c> qcList =new list<quote__c>();

list<quote__c> qpList =new list<quote__c>();
  
    public PCSReferToMetGAController(ApexPages.StandardController controller) 
    {
       this.accController=controller;
       acc=(Account)accController.getRecord();
        System.debug('Account Id ****'+acc.Id);
    }
    
     public void savePersonal()
    {
    system.debug('******Starting elements are:');
    selectedPersonal=acc.PCS_Personal_Line_Products__c;
    String[] s1;
    s1=selectedPersonal.split(';');
        List<String> plist=new List<String>();
    for(String s:s1)

    List<String> cList=new List<String>();
    for(String c:s2)
    {
    cList.add(c);
    }
     for(String i:cList)
    {
    Quote__c q1=new Quote__c();
    q1.PCS_Product_Line__c='Commercial';
    q1.PCS_Product__c=i;

    public pagereference save()
    {
    
    PCSReferToMetGAController p1=new PCSReferToMetGAController();
    
        System.debug('Account Id ****'+acc.Id);
       
        PageReference pg = new PageReference('/'+acc.id);
        
        pg.setRedirect(true);
