Help in aggr function!

[qlikviewforum]

Hi,

For one of the selections in the UI the below expression throws two values. How this is possible. Please explain! I'm not able to understand it.

aggr(  if($(vXYZ)  >  $(vABC),     

      (pow(10,floor(LOG10($(vXYZ))))),     

      (pow(10,floor(LOG10($(vABC))))))

      ,Business,Business_Unit)

this expression

calculate the result for each unique instance of Business and Business_Unit

and create a list of values for each unique value

so you should get a result for each unique instance
