Re: Weird error from contributed...

Adam,
I try your first suggestion deleting U after deleting uAvg that did
not work

Then I try your second one, I read the u and then average it and then
delete it works good. Computer tend to slow down whenever I try to do
this but it works!!!

thanks for the help.
