Hi, I have the problem: my EndNote adds unformatted citations only, it don’t format them (and citations don’t appear into the reference list, either). This problem is restricted to one certain document, inserting of citations into my other documents is correct.
I suspect you have inadvertently turned off CWYW (cite while you write). What version of endnote/word are you using? The place to look for where you turn it on differs. IN win 7 or later, word 2010 or 2013 it is right on the toolbar.
