Subversion Commit

[dheller]

I'm trying to add a Subversion step that will automatically perform a Commit, however whenever I test the step, it always fails with the message "Failed to create process: The system cannot find the file specified."
8/7/2007 6:56:24 AM: Building project step 'Subversion'...
svn.exe commit "svn://fortress:3698/Installation Master/TRIOS Install/trunk" --username dheller --password dean123 --force --verbose --non-recursive
Failed to create process: The system cannot find the file specified.

What file cannot be found?

My local working directory is C:\Installation Master\Trios

I have looked at the help, but I could not resolve the issue.
Repository tab
protocol: svn
host: fortress
port: 3698
path: /Installation Master/TRIOS Install
Subcommand tab
subcommand: Commit
executable: svn.exe
Files/Modules: (blank) I do not know what I need to enter in this field.
I want to commit everyting in the working directory TRIOS, Can you help?
