Send email to custom field

I have been able to find a few posts on this topic, but I am not a technical person and by the time I read through all the threads, I was totally and utterly confused. I still can't see, anywhere, a clear step-by-step guide as to how this should be done.

The best I've found is this:
1. Create an email field and name as required, e.g. Hidden Email
2. Under the 'Advanced' tab mark as visibility 'admin-only'
3. Set the default value under the 'Advanced' tab to {custom_field:wdf-email}
4. Go to 'Notifications' at the top of the page
5. Select the 'Email' radio button under 'Send To Email'
6. Insert a merge tag for the Hidden Email field, in my case {Hidden Email:5}
7. Set the 'From Email' and 'Reply To' as required

I'm assuming that in item 3, I select "insert merge tag: and in item 6, the 5 in {Hidden Email:5} means that field's ID.

I've done that and it all looks fine. However when I send a test email, it doesn't work. I get a confirmation message as if it's sent OK, but it doesn't go anywhere, either to the custom field email or to the email address I put in the BCC field. I don't get any error messages.

When I look at Entries, it's there. In the Notifications and Notes boxes, it allows me to resend a notification to Admin but not to anyone else.

I've just realized the problem. The form is not embedded in the post! Instead, the reader clicks a button to be taken to another page which has the form on it. Now I think about it, of course that won't work, unless there's a way to tell the form which post the reader came from - which I assume isn't possible?

I didn't really want the form embedded in the post itself, because it would make the post messy to navigate. Is there a way I could set up the form so it only shows the first input box, and the rest of the form would "unfold" below when the person starts filling it in?

I thought I could use conditional logic in the other fields to say that if Field 1 is not blank, the other fields should display. However that option isn't available.

Back again - I just tried embedding the form in the post. It works!

However I'd really like to get that form to unfold. Is there any way I can do something conditional?

Hello David,
I am using Gravity Forms for the first time and believe I ran into the same issue. I would like to use the "Enable Conditional Logic" to have my fields be hidden unless a prior field is filled. There are no specifications to the exact value, just as long as something has been entered, is there any way to do this?

Thanks,
Jessica
