Thanks for all your help here but still no joy. I replied to your message but just noticed that it was a message to myself, (????). I've tried a different browser, I use google chrome normally so tried IE instead, no luck. I've also deleted all cookies etc. still no good. LarkinPat1 has also joined in trying to help but although he says he has messaged me it hasn't appeard in my message box. This seems to be a bit of a thorny problem but I really do appreciate all your efforts. Thanks.
