DISTINCT Conflicting With My Query

I need p.phonenumber in there but then it messes up my DISTINCT ON m.number because I end up with dup m.numbers if I run just the inner select statement during testing.

But then I need the phonenumber in that subquery so that I can do list.phonenumber

ahh!



UPDATE Master
     SET master.homephone = list.phonenumber
FROM MASTER m
INNER JOIN
     (SELECT DISTINCT p.number, topphone.phonenumber
        FROM phones p
        INNER JOIN (SELECT top 1 phonenumber from phones) as topphone ON topphone.number = p.number
        WHERE    p.phonetypeID = 1
               AND ISNULL(p.good, 0) <> 0
               AND LEN(p.phonenumber) = 10
     ) AS list ON m.Number = list.Number
WHERE m.homephone IS NULL OR m.homephone = ''

Error:

Msg 156, Level 15, State 1, Procedure Skiaa, Line 66
Incorrect syntax near the keyword 'top'.
Msg 156, Level 15, State 1, Procedure Skiaa, Line 88
Incorrect syntax near the keyword 'top'.

I want to update m.homephone with the p.phonenumber based in the filtering critiria I have specified but this simple task is turning out to be a pain.
