Generate new multiple attributes!!!

edited November 2018 in Help
There are 3 attributes namely ID LISTINGS CURRENTVALUE...I need to report for every record, LISTINGS which lies between 0.8 and 1.8 of the CURRENTVALUE.

I would hope to generate a new attribute to hold each LISTING whose value lies in the following range(0.8 to 1.8 of the CurrentValue).

Thx

    Hello yes generate attribute operator is correct. The expression should be something like:

    if(CURRENTVALUE>0.8&&CURRENTVALUE<1.8,LISTINGS,"")

    Thank you Scott for the reply,but I require the system to loop through the CurrentValue (for each record) and provide me with an array of Listings.

    Dataset     
    ID  Listing  Current Value
    11A  ABC        600
    12A  DEF        400
    13A  GHI        800
    14A  JKL        200
    15A  MNO    1200

                          Range 
    .8*CurrentValue  1.8*CurrentValue
    480                            1080
    320                            720
    640                            1440
    160                            360
    960                            2160

    Desired output             
    ID        Listing          Current Value  NewVar1      NewVar2    NewVar3
    11A      ABC            600                    ABC              GHI 
    12A      DEF            400                    DEF            ABC 
    13A      GHI            800                      GHI              MNO 
    14A    JKL            200                    JKL     
    15A    MNO          1200                  MNO

    ok I don't think this is the most elegant solution (and the results are transposed from what you want) but here you go:
