TOC Question

[Joseph Hesse]

I am writing a book with separate chapters in a master document.  I 
added an appendix and it appears in the master document below a line 
that says Appendix. When I look at the TOC the appendix items do not 
have a heading before them that says "Appendix", just the lettered 
chapter in the appendix.  Is there a way I can get the word "Appendix" 
to appear before the lettered items?
Thank you,
Joe
