Thanks for the explanation Carole. I tried this, but it didn't work.

* In the combobox init
WITH This
   .AddListItem('<Sin Definir>')
   .List(.ListCount,2) = ' '
   .AddListItem('Matriculado')
   .List(.ListCount,2) = 'M'
   .AddListItem('Reservado')
   .List(.ListCount,2) = 'R'
ENDWITH

We met in GLGDW, remember? How are you? Thanks again.

Alex
