问题
So, I have this contact form sending me a mail and updating my google sheet. I found this on GitHub. When I don't add the JS file I get a mail and an update. When I add the JS I get neither. I have tried with and without this script link when using JS but it does not work.
<script
src="https://code.jquery.com/jquery-3.3.1.min.js"
integrity="sha256-FgpCb/KJQlLNfOu91ta32o/NMZxltwRo8QtmkMRdAu8="
crossorigin="anonymous">
</script>
For security purpose I have removed my google sheet link and kept it as action="#" from form and because I have added my e-mail in my google sheet I can leave my data-email="" as it is.
I also don't get the thankyou message at the submission of the form when I have added my JS file, but without it I get confirmation displaying the details submitted. There is a honeypot input label that is hidden by CSS and needs to be left blank for the form to be submitted successfully, avoiding spam.
It seems that there is some issue with the JS(duh!). Please help!!!
