multiple value selected in a combo box

I use a combo box as a filter.

          stFiltInstNo = "[idInstitution] = " & Me.filtInstNo & " AND "
          …
         Me.Filter = stFiltrer
         Me.FilterOn = True
   
 I would like to select multiple values in the combo box.

I tried to use MultiValued Field (MVF), but I don’t know how to extract values.
How can extract the values?

Is there a better way to do it?

Thanks

Check this example from Allen Browne: http://allenbrowne.com/ser-50.html
He is using a listbox rather than a combo box but the code will be near-identical.
While you're there, it's well worth having a look at the rest of his Access stuff.

You cannot perform multiple selections in a combo box.  You must use a listbox, or could use a subform in either continuous or datasheet format.  These later examples will involve some additional code, but are much more flexible.

I recommend using a multi-select listbox instead.  See my Access Archon article (with sample database) on this topic:

Here is a screen shot of the form:
