Ooops. Also change the column number where id kept. It was 2 ?

with thisform.cmbofficetitle_search  && Combo's name
<del>   m.myofficeId = .List(.ListIndex,3) && myOfficeId was a memvar</del>
   m.myofficeId = .List(.ListIndex,2) && myOfficeId was a memvar
endwith

if !empty(m.myofficeid)
   do form OFFICES with m.myOfficeId
endif

I'll explain by monday. Sorry.
