Sorry Derekm, No idea what I have done.

Hi Callie, no problem, it's very easy to post a question more than once, if your computer is a bit slower than usual, you can get the impression that it hasn't posted, and click ''send'' again, when a question is answered on the other posting, it will look like a separate question, and after 3 days, will appear in the 'unanswered'questions box, answering as I have, just helps to keep the box clear.
This is the second time I've posted this comment as well, no idea what happened to the first comment, Derek.

Thank you Derek,Thats probably what I did,I have just had a new computer,and still getting to grips with it,Thanks again,Callie.
