How to add a pictime Blogpost to my squarespace Blog

Hi, 

first: Hope my english is good enough to explain my problem/question. If you don´t understand what I´m up to, please ask!

I´m a photographer and I created a new Blogpost via Pictime. Now I have a HTML Code which I would like to add to single blog site.

(I want to do this again and again, so it´s not just a one-time-thing, I need a new blog post site for each new blogpost I create with pictime)

To do this I put up a new Blog Site, and used a block called "code". I put my HTML in the window which has popped up, but unfortunately this didn´t work out. 

Are there any ideas what I could have done wrong?

Thanks a lot
