Explained in simple terms.
I have created a calculator.
It consists of 6 input cell in which I enter values manually.
And many calculated cell with formulae in them which use the values entered
in the input cells.
How can I generate and error message if someone overlooks entering values in
one of the cells.....a text message that would indicate the missing cell or
cells that data has yet to be entered into?
Not sure the best way to approach this, any advise would be appreciated.
