Here's my objective:
Using a command button(s) automate an estimated calculation based on exisitng data and undo without using the Undo button. I am willing to break this into as many individual questions as needed, I just need your help in moving to another questions.
Using a command button(s) so that when the user clicks, a function is called to create the estimate then adding the estimate to another cell. If the user elects not to accept the estimate, have another command button that reverses the first action.
I know how to create a command button but macro drive or Active X? I will need help I creating the functions.
