I am currently using a speadsheet to perform a series of
calculations and generate a recipe. There are several key
inputs in different cells, and if the operator puts the
incorrect value, it can lead to problems downstream. Most
times the inputs are correct, but there are the
occassional accidents.

Let's say inputs A (in cell A1) and B (in cell A2) need
to be checked.

Before printing, I would like to prompt the user with the
values for those fields and ask for their initials (or a
CANCEL button to go back. Their initials would then be
entered into a cell on that sheet before it prints to
confirm the operator checked the values.

I'm fairly proficient with Excel, but not with VBA
programming. Any assistance would be greatly appreciated.
