# Re: [NTG-context] [NTG-Context] How to compute correct page number for handout

Thank you to answer my question.

I've tried it and I'm sorry to report that this only works in MK IV, that I
don't use (I've tried but some of my documents don't translate correctly).

best regards,
Pierre-François Bonnefoi.
