Thanks Ken, much appreciated.
As I'm a real rookie at all this stuff, I've another question for you. Can I have only one page on a site that can be set up like this? I've tried altering the code for different instances of the editor, i.e. <CE:Editor ID="Editor1"..... and <CE:Editor ID="Editor2" and then changing the vb code accordingly, but that doesn't seem to work.
Thanks
Bob
