I thought I saw in an add-in or somewhere where a slide bar was added to an
Excel worksheet, assigned a min and max value and associated with a cell.
Then by sliding the bar you change the cell value and the values of cells
using that whose formulas reference that cell. I am creating a game and
trying to determine a good starting population, land for housing, land for
food, how much food should each unit of land produce, growth rate, etc. so
you can see where it would be useful to have several of these to help me
"tweak" my numbers. Does anyone know what I am talking about and how can I
put one in my spreadsheet?
