Studio Theme - embeding objects in sidebar not being recognized.

Hello,
Using the Studio Theme and WP 3.0.1.
I'm a little stumped here. I am trying to embed a docstock conversion chart in the sidebar but I am not having any luck.
Once I paste the code in the text box it displays nothing.
The curious thing is that I am using embeded code for my streaming twitter feed and it works like a champ, but this is the second embeded code string I've tried to embed that doesn't display anything. The other is Social Mention stream. I've used both of these code strings on other sites with no problems.
I think I could wrap my head around it if they all didn't work, but why does the twitter stream work but not the others.
Anyone?
thanks
