I create a list, select the list type field.
in the field there are several types (type 1, type 2, type 3).
I need to be seen in the list of type1 and type2 only.
Create a Calculated Expression in the List Box and say
IF(typ <> 'typ 3', typ)
you can create the calculated expression by selecting Expression at the bottom of the list
in that object instead of selecting a field select expression and write :
if(typ <> 'type1' or typ <> 'type2', '', typ)
hope it helps
In your list box settings, tab General, choose the field expression and write this expression:
=if(typ<>'typ 3', typ)
Hope this helps,
