Running different macros from a message box

Hi All

I'm trying to establish a Word macro which opens a message box and allows the user to call Macro A or Macro B , depending on the choice they make in the message box.

The reason is that I have two macros which carry out similar functions but with small differences , and a turnkey message box would be a big help in running the correct one. Perhaps also a 'cancel' option to close the message box with no further action.

Can someone advise some code to satisfy this?

Grateful for any help.
