Keith,
Thank you very much for the points that you gave bob and I , although bob should get all the credit.
I get a bit sarcastic cause out of a 100% of the answers we give to this forum, we only get 5 to 10% return, this is why I said "no points for bob?" and i replied "I like getting points for no work!" cause most of the times we have to "work" or reply to many "?" to get a 5 to 10% return on the answers or in this case "points" = return.
In any case its all good and its fun to help other folks. I remember in the distant past where there was not help, you had to fend for yourself.
Keep posting and we will do the best we can and I hope we all can benefit!
Take it easy.
Jim
