How to adjust length of form

I'm trying out your form on our website and having issue with seeing all the way down to the bottom of the form. I'm using Xara web designer 11 premium as my editor. When I first created the form and inserted in page  could not see the submit button on the published page. I then went back into jotforms and reduced the length of the test box to one or two lines. That helped but now can't see your "created by jotform"at the bottom. I've tried reducing even further but still can't see your advertising at bottom. I would like to add more fields but when I do the submit and clear buttons disappear again. Need your help. Thanks

Hi,

Could you please try to re-embed your form on your website using the iFrame? You can find a detailed information about getting your iFrame code here.

Please check this and contact us again if the issue still persists. 

Awesome Owen that worked but now another
Is has come up. The same site has a "responsive web design" (meant for viewing site on small iPhones etc.) so basically when I make one change to the main site I have to make the same changes to the RWD side. The page form I created is a membership form and its works well in the normal site. I've copies and pasted the embedded code in to the mobile page but it not visible. I can see at the bottom left of the screen it trying to load the form but it doesn't show up. I'm using a web editor called Xara web designer 11 premium and the site is www.timminstaxpayer.com. Please help. Thanks

Could you please share the exact URL of responsive page where the form is embedded?
