Hi. I have a spreadsheet which calculates electricity usage and solar input etc.  As the price keeps changing I am putting the new prices into the spreadsheet.  I was thinking that I could use Scenarios or similar to be able to see what the bill would have been previously.  I have looked at the Scenario instructions but I'm not quite sure how to use it (bit rusty in Excel recently).  Is there a training video or similar I could watch.   Any help gratefully received. Regards Bluey
