If you use Wix, try adding paragraph tags before <p> and after </p> the snippet of code on your website. For example:

Another option would be to simply add a hyperlink on your Wix page (instead of the snippet) to link directly to the Bloomerang-hosted version of your form. You can access this hyperlink after you've built the form by going to your list of online donation forms in your Website Integration settings, and clicking View Hosted Form. That will open a new tab, and you can copy that url and hyperlink to it on your webpage.
