I know, but I dont want the macro to run as soon as I open the document. Have you looked at the document I have uploaded in the #6 thread of the posts called addpages.docm and understood what I want to achieve?

Example:
If a person opens the document "addpages.docm" and clicks on the grey line "No. of Units" the macro runs and ask "how many units". The user then puts in 5, as an example, from where the macro creates 5 pages of the page "2" content in the document and updates the Unit numbering starting with Unit 1 and ending with 5.
