I found code in the archives that works in that it requests a number and
then inputs that number into a cell. However, it doesn't have a cancel and
I haven't had luck getting anything to work for that. Since this code isn't
specifically for this simple purpose even though I was able to modify it,
however, it is probably better to start from scratch with code specifically
for this purpose.

So, the box should request the user input a number cell B4 but should have
nothing happen if the user presses cancel.

Thanks much! :oD
