need more details.
what do you mean by:
but its not working
it's not working to add that code to the content area?
or the code that you are adding to the content area is not executing the javascript correctly?
your code is a bit off. This is not correct:
<a href="javascript:;">
it should be more like:
<a href="#">
the onlick event is also calling a javascipt function:
MM_openBrWindow
you need to make sure that function is defined on the page for it to work.
