Formula Function that copies data from one sheet to another!!

Hi, im looking for a formula that will do as follows..

I have one spread sheet that has all my Parts list that need to be made and on another sheet i have a list of all my parts that are complete..

I want to automaticaly update my other sheet..

spreadsheet is broken in to sections..
