No To recordset or getting attachment

I can make a form that sends the text fields to & from a static email address, and uploads a file to the server. I can also make the From field dynamic from a Session variable. But if I link the To field to a recordset of email addresses it doesn't work. No error, just no message in the Inbox. And in no scenario (static or recordset From field) will it send the attachment.

I've gone into the Form Function tab and Edit the Send Email function, selecting a dynamic To field and selecting Submitted File in the Attachment section. But recordsets seem to be a problem, as does getting the attachment to go with the email.

Another thing that seems odd to me, is that if I select the Form tag and then Edit Form from the Properties area, when I save it, there are duplicate server behaviors. So if I edit it three times using the Properties panel, there are three Upload Files and Universal Email behaviors. Also, when I edited it this way, the Form Details section is correct, but the Form Function part no longer shows the From, To, Subject, Attachments or File Upload folder information. That doesn't seem right to me but I don't know if it's the reason I can't get attachments or send to a record set. I don't think that's the reason for my problems though because if I edit the Universal Email behavior directly using the Server Behaviors panel, and then go back, my entries will be there. But the form still won't send attachments or work with recordsets.

I’ve been trying different things all day, but am at a loss as to what to try next. Any help will be appreciated. Thank you.
