Run JS function after form validates on button click

Go one step at a time.... Remove everything besides div with id page1 and run ajax on button click (Remove onClick="metaSQL(); from button as well). Then post the result you get from console.log(data).

<script>    $(document).ready(function () {        $("#C1").click(function () {            $.ajax({                url: '/runPythonFunc',                type: 'POST',                data: {                    email: $('#User-Email').val(),                    entryTwo: $('#Algorithm-Name').val(),                    entryThree: $('#Algorithm-Desc').val()                },                success: function (data, status, jqXHR) {                     console.log(data);                }            });        });    });</script><div id="page1" class="page" style="visibility:visible;">        <!-- USER EMAIL -->        <label for="Algorithm-Name-3" class="custom-question algorithm-name">Enter your email<br></label><input type="text" class="text-field enter-name w-input" maxlength="256" name="User-Email" data-name="User Email" placeholder="Email address"                                                                                                               id="User-Email" required="">        <!-- ALGORITHM NAME -->        <label for="Algorithm-Name-3" class="custom-question algorithm-name">What will you name your algorithm?<br></label><input type="text" class="text-field enter-name w-input" maxlength="256" name="Algorithm-Name" data-name="Algorithm Name"                                                                                                                                   placeholder="Be as creative as you like!" id="Algorithm-Name" required="">        <!-- ALGORITHM DESCRIPTION -->        <label for="Algorithm-Desc-3" class="custom-question algorithm-desc">Briefly describe what your algorithm does?<br></label><input type="text" class="text-field enter-name w-input" maxlength="256" name="Algorithm-Description"                                                                                                                                           data-name="Algorithm Description" placeholder="You can still be creative!" id="Algorithm-Desc" required="">       <br><br>        <p><input type="submit" class="submit-button-2 w-button" id="C1" value="Add Animal" onClick="metaSQL();"></p></div>

take a try

async function function1() {    form.action = "/runPythonFunc";    await form.submit();    function2('page2');}
