Updating SQL table using an excel file

New to SQL.
I am trying to update a SQL table using an excel file which has 2 columns FMStyle and FMHSNum.
FMStyle is my link to the SQL table.
Here is what I have for code....
--------------------------------------------------
Update DataTEST.dbo.zzxstylr
SET hs_num = (select FMHSNum FROM OPENROWSET('Microsoft.ACE.OLEDB.12.0', 'Excel 12.0;Database=c:\temp\StyleHSCodesLoad.xls;HDR=YES ', [Sheet1$]))
Where FMStyle = zzxstylr.style
--------------------------------------------------
Everything seems to be ok except for the "Where FMStyle" is giving me a message Invalid Column name on FMStyle.
Do I need to qualify FMStyle?

Thanks
Michael
