Variable Input Dialog Box

To take the input from the user, I've been using an input dialog box for the required dimensions. I now need to get an input that changes, depending on the number of points they want to calculate, i.e. if they want to calculate 10 points, I need to get a property for each of those values.

Is there anyway to edit the input dialog box so that it will look for 'i' number of values?

Thanks!
