    Thank you for providing additional information. I did some tests in IE and FireFox and I was able to replicate the issue, form is not showing.

    In Chrome is loading fine, like you mentioned already.

    Try to add this code instead of DOCTYPE in your source code:

    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">

    And please let us know how that worked for you.

    We'll wait for your response.

    Thank you!

    I check your form's iframe embed code in firefox and its height is modified to zero whenever the form is loaded. That's the reason why the iframe container is not shown because its height is zero. There's probably something in your script that conflicts with the iframe element.

    Anyway, please try this fix.

    In your iframe embed code, insert this code inside the style attribute.

    min-height: 1640px;


    <iframe id="JotFormIFrame" onload="window.parent.scrollTo(0,0)" allowtransparency="true" src="https://form.jotformeu.com/61964451428360" style="width: 100%; height: 0px; border: medium none; min-height: 1640px;" scrolling="no" frameborder="0"></iframe>

    This might help. Let us know how this goes.
