Question: how do I add pages numbers to the in-text citations?

I want to add pages numbers in the in-text parenthetical
citations, but
every time I do they are erased when I save the text and
come back to it.
How can I do this?

 

Thanks,

Karen

Help!

I want to add pages numbers in the in-text parenthetical
citations, but
every time I do they are erased when I save the text and
come back to it.
How can I do this? I read the manual but I still don't get
it! I've wasted
the whole morning...

Thanks,

Karen
