    Narrowing a portal content



      Narrowing a portal content


           I cannot remember how to narrow a portal contents.


           I have a portal that displays student name, school year, school, grade


           I would like to have some global fields for school year, school, grade

           If the user select a school year, all students active in that school year would display

           If the user then select a school (along with school year), only students in that school year AND school would display

           If the user then selects a grade leve (along with school year and school) only those students active in that school year at that school in that grade level would display.


           I have a relationship between my Global Table and Student Table matching the 3 fields, but that requires all 3 global fields to be filled in to work (otherwise nothing displays in the portal).


           Any quick help would be appreciated.

               If your are using Filemaker 11 or newer, you can use the cartesian join operator in your relationship to match to all students and then use a portal filter expression referencing your global fields to filter the portal according to the values in those global fields.
