SOLVED Selecting a minimum value from another attribute range

Tom

Hi all,

I want to get the delta from the minimum value and other values from an attribute range. Example;

1000002 Leven 137
1000002 Leven -178
1000002 Leven 13786
1000003 Brand -10674
1000003 Leven -9386
1000003 Leven -9337
1000003 Brand -8311
1000003 Leven -8080

From the range 1000002 I want the delta between the lowest value and all other values in a new attribute/column. Then the same for 1000003 etc.

Anyone know how to do this?

Thanks and regards,
Tom
