Any help will be appreciated.

The value you are giving to the function .... $content

What is the value of $content when you call the function.

Well this is the script i downloaded from wordpress. Its pretty much suppose to display my clans roster on Gamebattles.com via the XML file. So I dunno what the developer did so I cant really answer that question.

No way for me to test anything, so you'll have to find a programmer who
can actually get into your files and test things out in real time. There is a
section on this forum where you could hire someone ... unless there's a
person that is willing to do it for free.

Ya I dont think a programmer will do that for free.
