Well Dave, that can be arranged with adverse or antagonistic comments. I was trying to explain the structures to the poster, but if I failed or said something inaccurate, I'll delete the post. Let me know. As I mentioned, I'm no expert.

Bruce, you seemed to be "right on the money" in your explanation IMHO. What's going on with you & Dave (only if you wish to say)?

Best Regards, George

Bruce, That was strictly tongue in cheek. No offense ment....:rolleyes:

Don't know. I took it as an aggressive comment, and I have no problem with deleting what I believe are good posts if they draw odd comments. But if Dave meant no offense, I'll accept it at that. The difficulty with these internet forums is that you get nothing but the written word without body language or voice inflection.
