Look at the repeater area demo, it includes setup for a file field.

I'm sorry I don't know how I can fix this problem
​
there is nothing special in the repeater area demo
I don't see anything

I cant't send my form on the forum : Error saving the attachment file.

What do you have in your file upload action? And if you do have a file upload action, perhaps because you want files to be uploaded to a different area than the default, have you turned off the "Upload Files" setting in the main Settings page for your form, since those two will conflict?

You can upload screenshot by using snag.gy

How has this been solved? Thanks.
