4. Form height - I would like the height of the form to be approx 700px, with the remainder accessible by scrolling. I have tried amending the height;1122px; below, to height;700px, but this didn't work upon publishing. Have I missed something? 

Hi,

Because the script included on the iframe embed code automatically calculates the total form height. You may re-embed your form using only the iframe embed code instead. And then change the scrolling attribute value to yes instead of no so the iframe provides scroll bar when the iframe height is smaller than its content. You can use the following.

<iframe id="JotFormIFrame" onDISABLEDload="window.parent.scrollTo(0,0)" allowtransparency="true" src="//form.jotformeu.com/form/41143967648363" frameborder="0" style="width:100%; height:700px; border:none;" scrolling="yes"></iframe>

Let us know if you have further questions. Thanks!
