Good for you. That is one thing I find interesting about so many things. Some times you can and should just wing it. Other times you go sailing along and only when you run into a problem do you figure out (in hindsight) that you the only way to do it right is 5 times more involved than you had realized! Oh well, I think I have been bitten too often to just wing this one and unless I hear of a better way I'll use the method I wrote about above. Thanks,

Joe
