Hello. I created a simple Javascript/HTML form and i want to submit the data to a Google Spreadsheet, link, but I am getting CORS error. I am not sure if I need to add some codes on my end or its something on Google App Script or some configuration.
The steps I did for the Google part is create spreadsheet > App Script > enter codes > Run > allowed permissions > Deployed, following this guide
I am not familiar with web app development especially this sort of stuff. Any help would be great.
