I want some help on creating a VB script for the following situation.

I have a excel file which has mutliple sheets for respective individuals.
I want a VB script which would allow individuals to access their respective sheet only (there by not letting them view the other sheets) based on their windows login.

So based on each person window's login, only the respective sheet in the excel file should be available to view & edit.

Would of great help if any one can get me this script.
