Hi - I am new to APEX, I have a query that looks like this. What am I doing wrong and how do I write a test case.

Thanks

public class GroupedQuery
{
    public string GroupBy1     {get;set;}
    public string GroupBy2     {get;set;}
    public string GroupBy3     {get;set;}
    public integer Count {get;set;}
    public Decimal Sum {get;set;}
    public Decimal Average {get;set;}
    public Decimal Min {get;set;}
    public Decimal Max {get;set;}

public List<GroupedQuery> queryResults {get;set;}

public List<sObject> queries = [Select b.Period__r.Name Name, SUM(b.Amount__c) Amount From Bud__c b group by Period__r.Name];
 {                                          
queryResults = new List<GroupedQuery>();
for (sObject query: queries)
{
    GroupedQuery myObject = new GroupedQuery();
    myObject.Count = Integer.valueOf(query.get('Amount'));
    myObject.GroupBy1 = String.valueOf(query.get('Name'));
    queryResults.Add(myObject);
}   }   }
