updating multiple tabs with a workbook

Hi there

We run a master spreadsheet tab containing details of a number of events that we produce, I then use some of the same information on two different tabs within the same workbook with more specific event and compliance information.

The master sheet runs in ascending date order, newly confirmed events are added into the time line by inserting a new row then the appropriate info, I'm looking for a macro/vba to enable me to up date the update the additional tabs following an update to the master while maintaining the timeline...

Any help would be greatly appreciated.

Thanks in advance!
