I embedded the code and all that comes up is this grey blob

Can you please share a link to the page where you are trying to embed this form, so that we may take a look and see if we can find a solution to the problem that you are experiencing?

As far as I can see from the screenshot, there are some typos in the code that you have used.

The aallowtransparency should be just allowtransparency, just one letter a.

The attributes of the iFrame should be separated by space, but there are no spaces showing on your screenshot.

The grey blob looks very much like a part of our internal error page. It would be very helpful if we could see the real page to see what the error message is saying.

The link should help very much, we will await your response. Thank you.

I've never done this before, can you tell? it's at vetsinthewild.com

but I'm not actually getting an error message.

and I am also unsure of where these "spaces" you speak of should go. I am a mere mortal with no special "web design" powers to speak of. Really, I have no idea why I was put in charge of this. 

Your proper embed code for Squarespace should be:

<iframe id="JotFormIFrame" onDISABLEDload="window.parent.scrollTo(0,0)" allowtransparency="true" src="https://secure.jotformeu.com/form/51403280486351" frameborder="0" style="width:100%; height:1746px; border:none;" scrolling="no"></iframe>

When I tried this code in my test site, it did indeed work using the steps in the following guide:

Also, make sure there is sufficient space at the bottom of your page to embed your form.

If this still does not work, try removing the theme you have applied to your page temporarily to see if that will allow the embedded form to show up.

If your form still will not show up, let us know and we will be happy to have another look.

ok thaaaaaaanks!

ok so this did work, exceeeeeeept that I can only see half of my text boxes, is this something I should change on my web page? or is it a coding problem?

this guy.....

It looks like the block you are trying add is quite small.  Try this code to see if you can force the width:

<iframe id="JotFormIFrame" onDISABLEDload="window.parent.scrollTo(0,0)" allowtransparency="true" src="https://secure.jotformeu.com/form/51403280486351" frameborder="0" style="width:650px !important; height:1746px; border:none;" scrolling="no"></iframe>

Also, if you can, adjust the size of the block you are embedding your code to.

oh ho ho ho ho David you are one smart son-of-a-gun! This is why I rescue wildlife, and you rescue idiots like me trying to do stuff on the google box.
