Include uploaded file name in send email block template

I have a form where I have text fields to be completed, and a file field to upload an attachment. When the form is submitted, the data enters in my table and the email is sent. When I receive the email in my inbox, all of the data apart from that of the file field is included. I don't want the attachment to be sent by email, just its name.

I'm using the standard WA block template with some edits.

How do I capture the name of the attachment that's been uploaded and display it in the email that is sent? Also, I am incrementing the name of the new file if one of the same name already exists, so I need to ensure I capture that new, incremented name.

Do I have to add code to the insert page and the email template, or just to the email template?

Thanks.

Don't worry Ray, I had a brainwave that seemed to make sense, and it worked!

I expected to have to create a session and populate it somehow, and then I remembered that there's a load of server variable options with the upload file field that I was able to choose from. I just chose the Server File Name option and that accounts for the incrementation if a duplicate file name is uploaded... who knew?

And, as I am typing this, it has just occurred to me that I have added this post to the wrong thread, so please move or delete as appropriate.

Thanks anyway.
