numering in endnote

I merged several documents into one and now I have references numbered 70 and 80 in the first paragraph how to I reorder the numbering so that references are called out in numerical order in the text??

Reformating the document, should reorder the references. Make sure you check which output style the document is using in the format bibliography dialog (this may be called something different in different versions of  Word, ie Word 2007 vs XP). 

 If that doesn’t work and if you have the original libraries that were used to create the original documents, you can unformat and reformat the document and references.
