Trying to clickable field that allows you to make call on cell phone

<div style="border: 1px solid black; border-radius: 5px; background-color: #0c5494; color: white; font-size: 25px; padding: 0px; margin: 0px; text-align: center;"><a style="color: white; text-decoration: none;" href="tel:240-691-6728">Call me at 240-691-6728</a></div>

Can I have a telephone link on my form.  You can see the form at 

https://form.jotform.com/80028349950156

Unfortunately, the "tel:123-456-789" href attribute is not supported in the Form Builder. It means that you cannot use it in the anchor tag <a>. The link will be ignored automatically upon saving the form. I tried linking an image but it is also not supported.

However, you can download the form's source code and upload it to your server. In this way, you can manually insert the link in the HTML code. Here's a guide: https://www.jotform.com/help/104-How-to-get-the-Full-Source-Code-of-your-Form.

Hope that helps. Thank you.
