Read or Change states of checkboxes values in a WebListBox?

IDE 2025r1
MacOS 15.3.2 on MBP16 M4

The IDE gives me WebListBox.CellCheckBoxValueAt(row,column) why i can’t use it ?

i need to read all values or assign values while populating the Listbox

The exemple from New Project Platforms>Web>Listbox>WebListBox ColumnTypes doesnt work

What do you mean “doesnt work”?
This is what I see:

and that checked checkbox is thanks to this code:

Me.CellCheckBoxValueAt(0, 0) = True

What the hell, i just retried it and it compiled … thanks and sorry
