Hi Maico,

Whether the group header change to the expected color is just depending on the value of the “Group Field”, although you add the “Aggregated Value”.

Let me make this more clearly, if you group a field which type is text and name is “Company” ,and use sum function to show an aggregate value using a number field “MyNumber”, there should be a group header’s text like this “Company:DELL; MyNumber: 100”. If you want to make this group header ‘s color change, you should go to the setting of color appearance of “Group Header”, and set the “Field Value” with “DELL”.
