SQL Enterprise Manager 8 And New Views

I get this error when trying to save the following view.  "View definition includes no output columns or includes no items in the FROM clause."  The select statement is below.  Any ideas?

SELECT     RTRIM(dbo.CUST.NBR) AS CustomerNumber, CASE NAM_FMT_FLG WHEN 'Y' THEN rtrim(FST_NAM) ELSE '' END AS FirstName,
                      CASE NAM_FMT_FLG WHEN 'Y' THEN rtrim(LST_NAM) ELSE '' END AS LastName, CASE NAM_FMT_FLG WHEN 'N' THEN dbo.trim(NAM)
                      ELSE '' END AS Company, RTRIM(CUST.ADRS_1) AS Address1, RTRIM(CUST.ADRS_2) AS Address2, dbo.Trim(CUST.CITY) AS City,
                      dbo.Trim(CUST.STATE) AS State, LEFT(dbo.Trim(CUST.ZIP_COD), 5) AS ZipCode, RTRIM(REPLACE(REPLACE(CUST.PHONE_NO_1, '*', ''), '-', ''))
                      AS PhoneNumber1, CustomerLastSales.LastSalesDate, CUST.LST_SLS_AMT, CustomerLastSales.TotalSales, CustomerLastSales.AverageSales,
                      CustomerLastSales.NumberofTickets, CASE ECOMMERCE_FLG WHEN 'Y' THEN 'Web' ELSE 'Catalog' END AS TypeOfBuyer,
                      LEFT(CUST.USR_DEF_NUM_FLD_1, 5) AS SourceCode, CASE CUST.USR_DEF_NUM_FLD_2 WHEN 'N' THEN ' N' ELSE ' Y ' END AS SendMail,
                      CASE CUST.USR_DEF_NUM_FLD_3 WHEN ' N' THEN ' N' ELSE ' Y ' END AS Rent
FROM         dbo.CUST LEFT OUTER JOIN
                      dbo.CustomerLastSales ON dbo.CUST.NBR = dbo.CustomerLastSales.CustomerNumber
WHERE     (dbo.CUST.CAT = 'MAIL')
