Thank you! I will email if I have any questions. I'm gonna have to call sooner than later. Dad went to the dr's yesterday & was told the strength in his legs is diminishing (which we all knew). My parents live in a split house so the Dr gave him a month to "move" to the lower level. Doesn't want him climbing the stairs. We all of course knew this was coming yet it is so frustrating!! Expecially for my Dad I'm sure!
