I have create some VBA macros, specifically a text box as follows:

Private Sub PlayPuzzle_Click()

    MsgBox "Play"
   
End Sub

when I select the text box I get:
 
This document was opened with Macros Disabled

A host application may disable or enable macros. This error has the following causes and solutions:

You opened the document with Macros Disabled.
Close the document, and then reopen it with Enable Macros.

For additional information, select the item in question and press F1 (in Windows) or HELP (on the Macintosh).
