I have wrote a basic macro.

What I wanna do is have a box pop up doing the following 3
things:

1 -Saying please enter id (this will enter an id into a
selected cell, type in number then click button ok)

2 -Button saying Dont know id which wil leave the cell
blank

or 3 -Button saying Cancel (this will cancel the macro and
I will assign code to undo the original macro.)

Hope you can help me

Many thanks
