Hi,
Below is the data structure of two lists (Heatmap and VDUList)
(Heatmap) and
(VDUList)
Values under Service Line are from VDUList. User will select unique Category values from a dropdown. Based on the selection, rating counts are to be listed. For Category-Network, if Rating falls between 1 to 5, then the count (2) should be under RED, if rating is between 6-7, then its count (2) should be under AMBER and if its 8-10 then the count (1) should be under GREEN. NA values are to be neglected.

Account in Scope will be the sum of RED, AMBER and Green for a specific VDU. FS in my case.
Kindly help.
Regards
