Get distinct column values into varchar value

Question

I have a large query, and in it a subquery in which I try to get all distinct rows from a temporary table column

(SELECT
        STUFF((
        SELECT DISTINCT #SomeTemporaryTable.CountryName
        FROM #SomeTemporaryTable
        WHERE (#SomeTemporaryTable.SomeId = 1
        AND #SomeTemporaryTable.AnotherId = 2)
        FOR XML PATH(''''),TYPE).value(''(./text())[1]'',''VARCHAR(MAX)'')
    ,1,2,'''') AS BreakDownLocationCountry,

The problem is that I am receiving the following error:

The ORDER BY clause is invalid in views, inline functions, derived tables, subqueries, and common table expressions, unless TOP or FOR XML is also specified.

Can someone please help me?
