Replicate information from one region to another

Hi,

I have two different pages Services and Gold Package. Services details information about all 3 packages (Gold, Platinum & Diamond) but they all have their individual pages also (same as above gold, platinum.. etc). I would like my client to only enter the information once.

I've already coded the Services page and added Perch so is there a way to pull in the information entered on the Services Page into the individual services pages? I tried using the same ID but that hasn't worked, any ideas?

Nate
