Hi Chuck,

As you know, Willum has also replied on this topic, and many thanks to you too for your reply.

All this goes to prove what a great forum this is with so many folk willing to help out. The way things are going I may be able to do the same before too long but first must go and open a tin of sardines..

Hey Fran,
The word you want is guru, and that's after eating just one sardine .

Best wishes, Peter
