I agree 100% with you. Sometimes it takes a lot of time to find the right answer and some people just can't be bothered to look up for it. I have been around for 1 1/2 years now and I will only post a question if I cannot find the answer I am looking for. And that involves some searching. Not just checking yahoo answers where you can never get a decent answer.

Anyway, your method sounds quite interesting and I have learned something new today, so many thanks 960kg
