CREATE DATABASE Script Doesn't Accept A Variable For A FILENAME

I want to create a SP that creates a new database, so I script-ed out the db and paste the script into new SP gui (SQL 2000). I want to pass it a variable for the data/log file location that is not the default location. The original script looks like this:

CREATE DATABASE [PWRR_DDS]  ON (NAME = N'PWRR_DDS_Data', FILENAME = N'F:SQL SERVER FILESDatabasesdbName.mdf' , SIZE = 3118, FILEGROWTH = 10%) LOG ON (NAME = N'PWRR_DDS_Log', FILENAME = N'F:SQL SERVER FILESDatabasesdbName_Log.LDF' , SIZE = 5000, FILEGROWTH = 10%)  COLLATE SQL_Latin1_General_CP1_CI_AS.

I replaced the path of the FILENAME variable like this:


CREATE DATABASE [PWRR_DDS]  ON (NAME = N'PWRR_DDS_Data', FILENAME = @DBPath, SIZE = 5000, FILEGROWTH = 10%) LOG ON (NAME = N'PWRR_DDS_Log', FILENAME = @LogPath , SIZE = 5000, FILEGROWTH = 10%) COLLATE SQL_Latin1_General_CP1_CI_AS,

declaring the variables as char(500). The error I get is "Incorrect sybtax near '@DBPath'.

Any ideas for workaround?

Thanks,
