To assist you with identifying them, the Err object is equipped with a property named Number. It throws me into debug.

We call the Range objects rng and cell. Isn't that more expensive than an elevated system? This statement tests the value of Err.Number and assigns some other number to N. Without knowing where the mouse is and when it (the exception/error) will appear (in which line of code) you would need to search entire house to catch it (run through the

A note on terminology: Throughout this article, the term procedure should be taken to mean a Sub, Function, or Property procedure, and the term exit statement should be taken to mean Both of the above routines exit the procedure, but sometimes, you'll want to continue executing the procedure — not exit it. This property works along with the Number property holding the message corresponding to the Number property. You don't have to declare a variable for this class.
