I copied and pasted it, but no matter what I do, the name doesn't change.
Have you re-loaded the library?
Actually it works when I change mine even without re-loading the library.
Do you have more than one library loaded?
Do you also have another macro that is for the 20 library?
I don't know why.
It is the UI_DIALOG line that creates the title.
If you now comment out those extra lines, does it stay showing 25?
I think it was just not updating for some reason.
Notice in your first image 3 titles were saying "Library 20".
Which makes me think the wrong library was loaded.
And now you have a completely different list of titles showing 25.
The image above is an image of the linked Custom-made Model View Options object. ^^
25 is the image I followed.
However, everything is handled behind the scenes.
If you succeed and delete that part again, the same phenomenon occurs.
I'm going to be satisfied with this.
Thank you Barry for always caring. ^^
