pb with attachment sent with the form

Hello,
I've created a new form but this time I would like the visitor to be able to send a file with the form.

I've added a "file field" in the designer part and in the setup part 've added a "files upload" action and enabled it just before the "checkrecaptcha"

when I try my form and attach a file there is no attachment in the email.
I added a debug part to see what happen here what it say :

    [chronoform] => contribution

what did i do wrong ?

Thanks in advance for your help

Thanks a lot bob,
It works perfectly now
I forgot to add the file input name to the Attachments box in the email action and I had a mix up with the order of the different action.

Thanks again
