exists update

[Dennis Malen]

Mark,

You are exactly correct as to what I want to do.

I will create a flag and message box that let's me know what the value of
"exists" is. Although I prefer to use a dummay variable to hold the value of
"exists", but I've been told I don't have to.

No one has indicated the processing I have submitted is incorrect. I have to
get to "firstL". No one has indicated my processing to get there is wrong.

What am I missing?
