Calculate TQ & BQ !!!!!

[#1]

Hi All ,

     I need to calculate TQ & BQ (TOp Quarterly& Bottom Quarterly)

i have Calculated column I.e; CINDEX1 i need to calculate TQ & BQ based on the CINDEX1 column

First I divided the CINDEX1 for the 4 parts it will give some value,and i do the sorting also in script it self

if it is first 459 i want add one more column in script  like TQ

other Wise BQ

See my attach file for more clarification
