Adding HTML to picture description

Hello, i am using a plugin ( Gallery Bank ) to show products that i offer with a description underneath the image. This box does not let me click “text” and insert HTML code but i was wondering if there was a way i could format this text.

I would like to add <p> </p> so the text would not all be con-jumbled together but i don’t think this is possible. If i am unable to do this using HTML text is there another way that any of you know of?

Thanks for any possible help!
