    Help with a Calculation for a Portal Record Set



      Help with a Calculation for a Portal Record Set


           Hoping Some one can help! I have an idea how to achieve what I need but have found others who help on the forum build much smaller less cumbersome calculations than me! Hope Im explaining what a need clear enough.

           I have a portal set to show 10 rows. if the portal has for example 21 records

           I have a field gRecordSet which when "1" is entered the portal shows record 1-10     "2" 11-20    "3" 21

           I want to set the gRecordSet field not to go over the needed record sets of 10  ie if 21  records then gRecordSet only goes up to 3



           If Child::PortalSum <= 10 and >= 1

              Set field    Parent::gRecordSet    "1"  (no other value can be added)

           If  Child::PortalSum > 10

               Child::PortalSum / 10

               average to nearest 1+                      (ie if portal sum = 21 / 10 = 2.1   result =3)


                field    Parent::gRecordSet         ( ie  field must only have numbers 1 2 or 3 to be able to be entered)
