The last few lines of text is cut off when I paste html into my Muse file.

See http://newmuirvalleysite.businesscatalyst.com/sign-page.html

I am pasting in the html for this my "MV Waiver" jot form into a new MUSE website, and the last few lines of text have disappeared along with the SSL seal.

Hi,

I tried to check your page it wouldn't seem to load for me.  In any case, here is our guide on how to add your form to an Adobe Muse page:

You may also want to try using the iFrame embed method, rather than the regular javascript embed:

If these do not work, let us know a working link to your page and we will be happy to have another look.
