    Try adding the text "!important" to your height value. Here's an example:

    <iframe id="JotFormIFrame" onload="window.parent.scrollTo(0,0)" allowtransparency="true" src="//form.jotform.ca/form/51510796015249" frameborder="0" style="width: 100%; height: 1200px !important; border: none; opacity: 1; visibility: visible;" scrolling="no"></iframe>


    See if that resolves the problem. We'll wait for your response.

    Yes, by adding the !important flag to some css attributes I was able to control the height.
