As you can see the quantity sum is the same for all the years, which shouldn't be the case, it should be unique for each year, how do i format it appropriately.

OP's code (taken from comment):

select (CAST(yearnumber as int)) as '@yearnumber'
      , min(convert(varchar(10)
      , cast(yearstart as date), 10)) as '@yearstart'
      , max(convert(varchar(10)
      , cast(yearend as date), 10)) as '@yearend'
      , ( select cast(weeknumber as int) as '@weeknumber'
               , SUM(isnull(cast(quantity as int),0)) as '@quantity' 
          FROM [meiForecasting].[dbo].george_mdx 
          group by weeknumber 
          FOR XML PATH('week'), TYPE
        ) 
from [meiForecasting].[dbo].george_mdx 
group by yearnumber for xml path('year'), root('years')

You did not show us how you are generating this XML, but - quite sure - you are doing this in some kind of string concatenation, or you have your dates as string values. Both is quite bad...

There is one big weakness in your XML: yearstart="11-24-13"

You should always avoid culture specific date/time formats. Even worse is culture specific with a two digit year. The worst are formats with language specific parts like 1 Dec 2016. Imagine a date like 02-03-04. Depending on the reading system you'd get numerous different values from this.

The proper format within XML is ISO8601. Using FOR XML will do this for you implicitly.

Check this. If it works, you just have to replace the @tbl with your actual table's name:

First I create a mock-up test scenario (you don't need this later)

DECLARE @tbl TABLE(YearNumber INT,YearStart DATE,YearEnd DATE,WeekNumber INT,Quantity INT);
INSERT INTO @tbl VALUES

--This is the actual query:

SELECT YearNumber AS [@yearnumber]
      ,YearStart AS [@yearstart]
      ,YearEnd AS [@yearend]
      ,(
        SELECT x.WeekNumber AS [@weeknumber]
              ,x.Quantity AS [@quantity]    
        FROM @tbl AS X
        WHERE X.YearNumber=tbl.YearNumber
        FOR XML PATH('week'),TYPE 
       )
FROM @tbl AS tbl
GROUP BY YearNumber,YearStart,YearEnd
FOR XML PATH('year'),ROOT('years')

And this is the result
