Generate new multiple attributes!!!

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

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

Scott

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.

Can you show me a piece of your example set?

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:

Thx Scott, I was hoping for a operator based response ,yet I will give this a try.
