Hi,

I have a spreadsheet which I am looking to distribute to a few people.

It basically tracks stock prices and works out portfolio value and tax implications.

The spreadsheet has code and data, and I want to know the best way to arrange it so that I can upgrade the code later if need be, without overwriting the data.

I suppose I need to split the two up, using an add-in?

What is the best way to do this please.

Thanks
Rich
