Forcing an error message under the "Submit" button

On my Contact Form, the CAPTCHA simply reloads if a user does not enter a valid email address. You have to scroll up to actually see the error message under the email field. The analytics for users who access my form versus the number of completed forms is vastly different.

I think people assume their form was sent even though they never received a confirmation message, because it is not obvious that they still have to complete a required field. While I was testing the form, I sat there hitting “submit” multiple times waiting for an email to come, and then I scrolled up and happened to notice the required field error.

This is the code:

<div class="form__section">
        <h2 class="form__section-heading">01. Contact Info</h2>
        <div class="form__group">
            <div class="col-1-2">

            </div>
            <div class="col-1-2">

            </div>
        </div>
        <div class="form__group">
            <div class="col-1-1">
                [text address_1 placeholder "Street Address Line 1"]
            </div>
        </div>
        <div class="form__group">
            <div class="col-1-1">

        <div class="form__group">

How can I have an error message show up under the Submit button that says something like “Please scroll up to fill out the required fields”
