Unsure of how to proceed to submit changes for a project

Jul 14 at 7:32 PM
Hello,

At the risk of sounding totally stupid, I need help in trying to figure out how to use the CodePlex site.

I joined a project and submitted a pull request and explained what changes I made to the project source code. Someone replied to that request and said "There was no commit for this. Can you resubmit? I would like to see what you changed." I replied to that message explaining that I am new at this and need more information about what to do next. He never replied back.

Can anyone tell me what that person is asking for and how I go about doing it?

I tried reading the documentation to figure what it is I am supposed to do, but I'm still unsure of what I am supposed to do.

Any help would be gratefully appreciated.

Thanks,
Tony
