Unclear referee's message I receive a message from a referee, but I didn't understand what was required of me exactly. The message is:


  please check again the typeset text of these lines


What kind of error do they refer to?
The message is vague, but check the text the referee has highlighted. Chances are you can see something wrong. The word "typeset" here could indicate a typesetting error - for example, perhaps you forgot to include a reference that the text cites (this makes LaTeX go [??]). Or it could just mean there's a spelling error, an ambiguous sentence, etc.

Either way, the reviewer pointed out which lines they're referring to, which should help you solve the issue.
