Limiting Scrolling Area On A Worksheet

When I limit the scrolling area in a worksheet, and it works there and then, when I close and reopen the whorkbook, the limiting does not work.

This is how I do it:-

I Right-click the sheet tab for the sheet which I want to place a limit.
In the resulting Context menu, I choose View Code. The VBA editor appears and asks for the password to view the code. I keyin the password

I then set in my limit as B2:O25

Then I close the VBA Editor and display the worksheet where I try and I find it working.

I close and save the workbook.

When I reopen the limiting has disaapeared!
