I don't know where oyu get the N/A from? Create a command button, right
click on it, select View Code, and enter the following: Range(<your range
eg"A1">).ClearContents. Close the VBA editor, click on the Design icon, (the
one with the pencil, triangle and ruler), and click on the button. It will
clear the contents of the cell. I did not deal with naming the button etc
though.
