General ⇒ Problem wit references when build the file

[kost]

Hello,

I have problem with references and citations. When I try to build the file, it could not to build it whole to the end, and in Output field there are warnings like this -
"LaTeX warning: Reference ´Milestones´ on page 65 undefined on input line 1324"

There are warnings with each reference or citation which I have in text...

I had not problem with this yet in this file. Everything were OK, but now I do not know what was happened with this...

Thanks for help.
