You might try the batch manager to replace some text....not sure if it will work, in your particular case but I have used it successfully in similar incidences ...worst case is page by page with an editor that has "Find and Replace"....some editors will batch process.
Where abouts is the anchor tag shown in the DHTML Editor? Sorry, I can't seem to find any reference to "a href="index.htm">Home</a> in it where I need to change.
Yes, it was the onclick event! I didn't think that I had any onclick events until I checked the main page settings and the events in the body as per s.dav suggestion.
Obviously I had been playing around with it, thought that I'd removed it but hadn't and it had copied to each page when I was using the first as a base template [2 ??:-|]
Anyway removing the onclick events seems to have done the trick, all is running well now.
jtarin - thanks for your help - does the syntax error still show up or is that fixed now as well? I'd check it myself but not sure how to?
Thanks again, this forum is very helpful, you're lifesavers!!!!!!!! Much appreciated.
