Fillable form - submit button won't work

[AaddiaJ]

I have created a fillable form with the submit button with mailto: email address.  The form works perfectly on my desktop, but when I upload it to our website everything works but the Submit button. It is not clickable at all. Any suggestions on why it is not being recognized when uploaded to our website?

If the users of the PDF form will be opening it with web browsers, it won't work as intended.

The modern family web browsers have their own native PDF viewer and it won't render (nor respect) the Acrobat JavaScript code embedded in that form.

The only web browser that seems to actually respect a PDF that uses the "mail to" method with Acrobat JavaScript is Microsoft Edge web browser.

In which case, you can test how the PDF behaves if it is used with the MS Edge browser.

If it works, you need to encourage your users to use Microsoft Edge.

I am aware that this may not be the answer that one would expect as a solution, but it should work with that browser  (and until Google Chrome, Opera, Vivaldi and Mozilla Firefox, for example, get up to speed).
