selected conditional fields (Email)

Both problems should be easy to solve. Can you set up your form at https://conditional-fields-cf7.bdwm.be/form-tester/ and share the link here?

Problem 1 has likely something to do with the fact that all field names should be unique.

Problem 2 can probably be solved by adding first_as_label to your select element. (more info: https://contactform7.com/checkboxes-radio-buttons-and-menus/#select)

I see you are using the plugin Ultimate Addons for CF7.

This plugin tries to solve the exact same problems as Conditional Fields (Pro) tries to solve. But because they overlap so greatly, it’s impossible to make them compatible. You will have to choose to either go with Conditional Fields or with Ultimate Addons for CF7, but you can’t use both.

Just like you cannot create a website with both WordPress AND Joomla, you cannot create a form with both Ultimate Addons for CF7 and Conditional Fields. Even if you manage to make it work now, it will break with almost every update.

Alright. I took the liberty to remove all the uacf7 stuff from your form.
You are using some invalid code though. I tried to fix the most obvious errors.

Code like this is not valid:

[select my-select placeholder "one" "two" "three"]
[text my-text placeholder "hi" "hey"]

So I corrected most of it to:

[select my-select first_as_label "one" "two" "three"]
[text my-text placeholder "hi"]

Here’s the fixed form: https://conditional-fields-cf7.bdwm.be/form-tester/?hash=cabde399646cf54bf0174287cc590c1a

However, to get a good understanding of your errors, it might be better to make this form a lot more simple, so it’s easier to point out where and why you are using incorrect patterns.
