Hi,

You can use 'Data Validation'.

Select the cell(s) then

Data|Validation - In the dropdown select 'Whole number' and then set your
parameters in the boxes.

Click the 'Error Alert' tab and create a custom message.

When competing hypotheses are otherwise equal, adopt the hypothesis that
introduces the fewest assumptions while still sufficiently answering the
question.

I was wondering how to have excel have a specific number input only. For
example I make a grade spread sheet, and I have where I can put grades on the
horizontal row. Is there a way, where only the numbers of 1 though 100 can be
imputed and nothing else. Like if I put over 100, it would say error or not
allowed or something? I realize I can lock everything else, But I still want
it, so it will keep it within a data range, encase I make a mistake or
something and excel could pick it up.
