Thank you, Bob, for the apology. I wasn't offended by your or anyone else's remarks. We all fail, at times, in how we respond to others. The great thing about the members here is that most are able to admit that they may have had a brain cramp & sincerely offer an apology or explanation to what they wrote. My response was an effort to get the thread back on track & maybe my response was also a little harsh, so, my apologies, as well.
