Hello!
My question is:
I am using a Bubble plugin “multiselect dropdown”. I don’t find videos tutorials 
I have created an option set (OS_SecteurActivite_Compte) with different options
I placed my multiselect in a popup and I would like the user to be able to choose multiple options in my multiselect dropdown input.
I have created a workflow to call/create from the database and a workflow to modify it (CRUD)
The problem is that I don’t understand why it is highlighting in red the value that I indicate in the creation of the field OS_SecteurActivite_Compte = Multidropdow compte secteur activite’s value
- What is the error? Can you please correct it. Thank you
- Are there any other solutions?
- Can I do the same thing with a simple dropdown?
THANK YOU 
Problem, Why not ok → field OS_SecteurActivite_Compte = Multidropdow compte secteur activite’s value
What does the issue list say? Multidropdown’s value is most possibly a list. Maybe you field in the db is not a list?

hover over the expression and you will see what it evaluates to…and when you do that it is not obvious, but it is there, which is whether it evaluates to a single item or a list of items…in your create action you are attempting to add a field that expects a single value a list, so either give it a single value or create a new data field that is a list.

Thank you guys for your explanations. It makes sense…
I learn something new every days.
I changed the OS to List and now it works. Thank you.
