• How can I apply the custom code to this following expression?

    =((Sum(Fields!test1.Value) / Sum(Fields!test9.Value) * 10 + Sum(Fields!test2.Value) / Sum(Fields!test9.Value) * 10 + Sum(Fields!test3.Value) / Sum(Fields!test9.Value) * 10 + Sum(Fields!test4.Value) / Sum(Fields!test9.Value) * 10) – (Sum(Fields!test5.Value) / Sum(Fields!test10.Value) * 10 + Sum(Fields!test6.Value) / Sum(Fields!test10.Value) * 10 + Sum(Fields!test7.Value) / Sum(Fields!test10.Value) * 10 + Sum(Fields!test8.Value) / Sum(Fields!test10.Value) * 10)) / (Sum(Fields!test5.Value) / Sum(Fields!test10.Value) * 10 + Sum(Fields!test6.Value) / Sum(Fields!test10.Value) * 10 + Sum(Fields!test7.Value) / Sum(Fields!test10.Value) * 10 + Sum(Fields!test8.Value) / Sum(Fields!test10.Value) * 10)
