Foster > Paul Thank you for your reponse. I will admit I get a little fuzzy on the single v double quotation marks, generally the rule I go by is if it is a string, I use singles, if any processing I use doubles. I am not recalling why did it that way, perhaps I had doubles and it did not work so I was whittling down the options.... Thank you again for your help.
