How to get my divorce lawyer to return my calls?

I'm in great need of how to handle un-answered phone calls from my divorce lawyer. There was an error in my divorce decree, and I've left numerous messages with her secretary, but still no reply and the decree has not been changed. The courts say she has to correct the error or it will cost me money. What should I do? The divorce took place in January of this year.

Perhaps going in to the office in person and asking to see your lawyer might be an option?
