I have a problem with my code, can you find a solution for this code?

I want to take one of the Position and Cost From Dance.Sector1.Position and Cost ...

But, I didn't understand the last code. Can anyone help me :(

if Scout.Position(i,1) <= qrmax && Scout.Position(i,1) >= 0  
      if Scout.Position(i,2) <= qrmax && Scout.Position(i,2) >= 0
     Dance.Sector1.Position(i,:) = Scout.Position(i,:);
     Dance.Sector1.Cost(i,:) = Scout.Cost(i,:);
     Dance.Sector1.Position = Dance.Sector1.Position(all(Dance.Sector1.Position ~= 0,2),:);
     Dance.Sector1.Cost = Dance.Sector1.Cost(all(Dance.Sector1.Cost ~= 0,2),:);
      end               
  end
    if Scout.Position(i,1) <= qrmax && Scout.Position(i,1) >= 0  
        if Scout.Position(i,2) >= qrmin && Scout.Position(i,2) <= 0
       Dance.Sector2.Position(i,:) = Scout.Position(i,:);
       Dance.Sector2.Cost(i,:) = Scout.Cost(i,:);
       Dance.Sector2.Position = Dance.Sector2.Position(all(Dance.Sector2.Position ~= 0,2),:);
       Dance.Sector2.Cost = Dance.Sector2.Cost(all(Dance.Sector2.Cost ~= 0,2),:);
        end
    end
    if Scout.Position(i,1) >= qrmin && Scout.Position(i,1) <= 0  
        if Scout.Position(i,2) >= qrmin && Scout.Position(i,2) <= 0  
       Dance.Sector3.Position(i,:) = Scout.Position(i,:);
       Dance.Sector3.Cost(i,:) = Scout.Cost(i,:);
       Dance.Sector3.Position = Dance.Sector3.Position(all(Dance.Sector3.Position ~= 0,2),:);
       Dance.Sector3.Cost = Dance.Sector3.Cost(all(Dance.Sector3.Cost ~= 0,2),:);
        end      
    end
    if Scout.Position(i,1) >= qrmin && Scout.Position(i,1) <= 0  
        if Scout.Position(i,2) <= qrmax && Scout.Position(i,2) >= 0  
       Dance.Sector4.Position(i,:) = Scout.Position(i,:);
       Dance.Sector4.Cost(i,:) = Scout.Cost(i,:);
       Dance.Sector4.Position = Dance.Sector4.Position(all(Dance.Sector4.Position ~= 0,2),:);
       Dance.Sector4.Cost = Dance.Sector4.Cost(all(Dance.Sector4.Cost ~= 0,2),:);
        end      
    end
    if Dance.Sector1.Cost < GlobalBest.Cost       
       GlobalBest.Cost=Dance.Sector1.Cost;
       GlobalBest.Position=Dance.Sector1.Position;
    end
    end	

The last if statement is my problem :(

It's saying if the current cost is less than the master, overall, global cost, then replace the master, overall, global cost with the current cost. And also to record/log the position where that occurred. This will let you examine all the costs and find the overall lowest cost.

yes I know ... but at the end if statement I have an error :(
this is the error message (Reference to non-existent field 'Cost'.)

Well, there is no Cost field. Put a breakpoint there and then when it stops, examine the variable in the variable editor to see what fields it does have.
