Checkbox lookup table selected and put in a simple select list

Hello,
I have a checkbox Lookup Table (name: 'list_methodes') with the lookup table 'methode'. I want to retrieve the selected values in 'list_methodes' and load them into a Multiple choice lookup Table (name: 'top_methode_1') still using the lookup table 'methode'. How can I do this?

Thank you for your assistance.

It looks like you've almost got it, though I believe the arguments to selected are in the wrong order

Also, what is choix_methode? I'd expect the "Filter" expression to reference the "Liste des méthodes" question directly, like

selected(liste_des_methodes, id)

Ow, thanks a lot man. Save my day
