master checkboxes to select a group of other checkboxes?

hey, I'm making a list on excel, it's actually 5 different lists in sequence, and each one of them will have a master checkbox wich selects all the checkboxes that are slaved to each item on it's list.

I'm listing songs, and each list is a different album, so I want to be able to select each song separately (already done) select every song of an album at once, and also select all songs from the 5 albums, so I'd also need to have a master checkbox that selects "sub-master" checkboxes.

I saw this tutorial Link but it's only helpful for selecting everything, so I also saw this post: Link but there must be a syntax error or something, and maybe I also don't quite understand it very well to apply it to my needs, because it returns an error message.

any help is appreciated!

thanks, but yeah, I don't know what exactly to do to adapt to my file, then sure I'll send my list, here it is:

I have assumed that any row with a formula to calculate time of selected songs is an album title with a master checkbox, and that the Total at the bottom is the Master Master. This solution is flexible so songs and albums can be added without changing code. However, your checkboxes for album titles and Total need to be linked to cells, just like the song checkboxes. Also it depends on the formulas you are using to add the total times, so the code can navigate and figure out what's an album title vs. what's a song. So be aware that if you change your formulas then you need to update code.

I also corrected the formatting on your bottom total.

thanks mate, that's pretty much everything I wanted. I did notice that adding songs work just fine, as you said, so thanks again.

cheers

Hey, I'm revisiting this thread, because I wanted to add another album to the list, but apparently I can't manage to do that, it bugs out the checkboxes. While adding more songs works fine, a whole album is a problem. How to do so?
(in fact it's not an actual album, but just another category to include songs that don't belong in an album).

thanks in advance

The code is OK. You have to be aware of several things when you add data. I have attached an example with another album added.

To add an album:

Insert new lines above the "Total" row
Copy the formula in column C for the total selected time to the new album row
The checkbox on the row for the album must have an assigned macro of 'Repert鏎io Completo com tempo.xlsm'!AlbumCheckboxClick
The checkboxes in the rows for the songs must have no macro assigned
The checkboxes in the rows for the songs must be linked to the cell in column A of that row

If you do all those things it should work. I think it's possible to automate the insertion of new albums and songs, but I'm afraid I don't have the time at the moment to do it for you.
