SQLCMD help with SYNTAX... using SQL SCRIPT.......?

Experts:

I'm using the following SQL Script that uses the SQLCMD to run another SQL Script...then save the results in a .CSV file.....

DECLARE @date char(1000)
DECLARE @sqlcmd varchar(8000)
DECLARE @savefile varchar(8000)
SET @date = (SELECT REPLACE(CONVERT(VARCHAR(10),GETDATE(),101),'/',''))
SET @savefile = ('\\sqlstation\ftp\WOWCO_HMB_HMTB_'+@date+'.csv')
SET @sqlcmd =
'sqlcmd -S 192.168.10.4 -U mavega -P vega1 -i "\\sqlstation\ftp\calldataimport.sql" -o "\\sqlstation\ftp\WOWCO_HMB_HMTB_'+@date+'.csv"'
EXEC master.dbo.xp_cmdshell @sqlcmd

I know it can work..but the problem I'm having is trying to assign the SAVED FILE NAME using the GETDATE() formated within the filename.

Can someone take a look at the syntax for this section:

-o "\\sqlstation\ftp\WOWCO_HMB_HMTB_'+@date+'.csv"'
EXEC master.dbo.xp_cmdshell @sqlcmd

I'm trying to have the results SAVED in this filename format:

WOWCO_HMB_HMTB_02122008.csv

SQL keeps telling me this:

Sqlcmd: Error: Error occurred while opening or operating on file \\sqlstation\ftp\WOWCO_HMB_HMTB_02122008                  
   .csv (Reason: The system cannot find the path specified).
         NULL              


The above 3 error lines aer separated in the error....???

Thanks
