How can I embed this on the description

So, I created a block that actually pulls a soundcloud track.

What I need now is to put the result of that block on the same div as the group description:

group file has:

<div class="bx-def-font-large">

__bx_artists_block_soundcloud__

        __description__

</div>

my block has _bx_artists_block_soundcloud

tried

<div class="bx-def-font-large">

                __bx_artists_block_soundcloud__ 

        __description__

</div>

 but no go

How can I possibly do this?  

(artists is just a copy of the groups module)

what do you mean by you "created a block"? could you post a screenshot

basically on my groups module I have another "feature"

When in editing mode I have a field: Track

that is saved on the DB tables related to that page and then is pulled using :

and is displayed on the page as in below

The reason why you see the player without a div around it is because Ive set the div as hidden, but then I had the issue with all the space on top and bottom, and after trying and trying css modifs to remove that space is too much pain as it always affect other divs...

So the thing I am now trying to do is to put the player inside the "description" div

Hope you understand

Edited:

The source code where "I'm stuck"

The solution is to set the block to use design box 0; you can do this in the database or use a module such as Deano's Block Tools (I think there are also other modules in the market as well) to set the design box to zero.  Design box 0 does not have the header and footer and is useful when you want a simple block.

 Thanks very much for the hint, geek_girl

ended up finding this post on how to create a new design box and make use of it from deano92964 and worked like a charm. also learned how blocks work for once ...
