My latest app - European Space Agency News (featuring Bing Translate) is now in he Windows Store

Question

My latest Space News App.. European Space Agency News now in the Windows Store
http://apps.microsoft.com/windows/app/european-space-agency-news/092f5794-8705-49bc-b27e-17ad5fd754b2
The European Space Agency (ESA) is Europe's gateway to space. Its mission is to shape the development of Europe's space capability and ensure that investment in space continues to deliver benefits to the citizens of Europe and the world.
European Space Agency News features nine topical news and image galleries from the ESA and 19 "news from member countries" galleries. Since the news from member countries was presented in the language of that country, I used an in app translate
function so that news in each gallery can be read in multiple languages (languages supported by Bing Translator).

thanks, yes, am using a free key. I can't afford to pay for keys.. The syntax
for the Title works great. Thanks.
I tried the following for the description, the syntax doesn't throw any errors,
but the content is still blank. The feed is from
http://www.esa.int/rssfeed/TopNews
If (IsEmpty(TopNews), "Loading...", If(Dropdown1_24!Selected!Value = "en",
BingTranslator!Translate(Mid(ThisItem!description!'$text',Find("<p>",ThisItem!description!'$text')+3,Find("</p>",ThisItem!description!'$text',Find("<p>",ThisItem!description!'$text'))-(Find("<p>",ThisItem!description!'$text')+3)),
Dropdown1_24!Selected!Value)))
 Can you tell me what I've done wrong?
