The end of the May 30–June 5 Week is a bit weird due to the fact that the final song in the workbook is exceptionnaly this one: "New song for 2022 Convention" with no number.
I have found this alternative solution:
In the parameters, section "Songs", I have created a song #999 called "New song for 2022 Convention" and in Parameters, section "Life and Ministry Meeting"/"Schedule", for the week Date "2022-02-30", and "Song 3", I have changed -1 in 999
It's not perfect because when I print the Workbook, we can see the strange song #999. We can improve that via a modification in the template.
Maybe, one of you, guys, has a better solution
