Brett,
If you "group" the sheets, whatever happens on one happens on the other. You can group sheets in two ways. If you want to group two (or more) sheets that aren't right next to each other, click on the sheet tabs while holding down the Ctrl key; you should see each tab that you click on hilighted. If the sheets you want to group are all next to each other you can click on the first tab, hold down the Shift key and click on the last sheet and all sheet tabs from the first to the last will be hilighted and included in the group.
This is a very useful but "dangerous" technique. Remember, whatever you do on one sheet in the group will also happen to the others.
have fun
No the grouping doesnt work unless i can have them grouped at all tims and also the way the sheet is the master sheet has several columns but only one relates to each of the secondary sheets. So i need to link the data in the diff columns to diff sheets.
