What is JotForm?
JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
At JotForm, we want to make sure that you’re getting the online form builder help that you need. Our friendly customer support team is available 24/7.
We believe that if one user has a question, there could be more users who may have the same question. This is why many of our support forum threads are public and available to be searched and viewed. If you’d like help immediately, feel free to search for a similar question, or submit your question or concern.
Sorry to say but SmugMug does not allow its user to input any scripts (such as iFrame or Jscript) on their site due to their strict security policy in place. This means you would be required to use the direct link for the form instead of embedding it onto your website.
You would have to use the HTML Tab to insert the script provided below.
<a target="_blank" href="http://www.jotform.me/XXXXXXXXXXX" rel="nofollow">JotForm Form</a>
You can access the direct link to your form by carrying out the instructions below.
I hope this provides all the information you need. Feel free to ask for further support if needed.
