Keeping a page number in a text box updated
I have tried googling first, but I don't even know how to word this.
I have a text box in a book I am doing that says
Serve as is or cover with the mole sauce (see page 165).
Is there a way to keep that "165" updated automatically as the page with the mole sauce changes page numbers (because pages being shifted, etc) Just like there is a way to keep table of contents constantly updated, is there a way to do a single number such as this?
Thank you in advance
Oh, this is in CS6 for mac.
