Aylin,

Are you sure this is not null when it is posted back.
(Request.QueryString["centerId"]!=null)

And so we can go on with a lot of questions, I think that it is a better
approach to try it first with a program that has less functions. That makes
it for people active in this newsgroup as well easier to see where the error
can be.
