The questions arose, Helen, because you highjacked the thread of another person with a "similar but different" question. That's why Robert told you you should have started your own thread. That is simply forum courtesy and keeps things from getting confusing to everyone involved.
That said - it sounds like you misinterpreted the "refresh" instruction. After purging your forum cache from the ACP, you were supposed to "refresh" your browser cache
to see if your changes were made.
You should now do as Robert suggested and start your own topic and start by completing the Forum Request Generator
so we have a link to your site to see exactly what you have done so far.
