Problem specifying file when creating db through osql

[gny]

I'm trying to create a new db, specifying the FILENAME. This works great, except i need to do it through osql. When I do, SQL Server seems to ignore the FILENAME and creates the db in the default data folder.
Does anyone have any ideas?

SET @sSql = 	'CREATE DATABASE ' +
				+ @sDB_Namn + '
			ON
			(
				NAME = ' + @sDB_Namn + ',
				FILENAME=''' + @sPath + '\' + @sDbFileName + '''
			)
			LOG ON
			(
				NAME = ' + @sDB_Namn + '_Log,
				FILENAME=''' + @sPath + '\' + @sLogFileName + '''
			)'
	PRINT @sSql
	SET @sCommand = 'isql -U ' + @sPriviligedLogin + ' -P ' + @sPriviligedPassword + ' -Q "' + @sSql + '"'
	EXEC master..xp_cmdshell @sCommand
