Skip,
not sure I know how to do what your saying because I'm lost with functions but ....
if a write a sub routine that sets all my variables to nothing and then call it each time I want to set them to nothing.
is that it? that is not a lot of work and will help me as there are one or two I may not want to set to nothing.
simple idea, I did not think of it.
thank you
