no worries and no need to apologize we are all learning no matter what level. IMHO no such thing as a stupid question or wasting people's time on the forum... most are happy to help and clarify or point us in the right direction. Sometimes a little fun is had at other's expense but it is all meant in good spirit and camraderie and members can usually take as much as they dish out. keep enjoying the forum and keep asking: it can only add knowledge (for questioners, responders, lurkers) and improve everyone's game. -Keith
