Обсуждение: Can't work out what is wrong with this code

Hi,

I'm trying to return a row from a table and I'm having a tough time working out how to do it.

Here is my code:

When I try and call the get_blog function in JavaScript I just get undefined which is not very helpful. Can someone
pointme in the right direction please? 

Simon.
