Question: What is the FCC info for the call sign with a frequency MHz of 101.3, a ERP W over 10, and a Facility ID smaller than 87027?
Formula: LET(query1,SUMMARIZE(H1,SUMX(B1),SUMX(E1),SUMX(D1)),FILTER(query1,(CHOOSECOLS(query1,2)=101.3)*(CHOOSECOLS(query1,3)>10)*(CHOOSECOLS(query1,4)<87027)))
Formula2: LET(query1,SUMMARIZE(H2:H8,SUMX(B2:B8),SUMX(E2:E8),SUMX(D2:D8)),FILTER(query1,(CHOOSECOLS(query1,2)=101.3)*(CHOOSECOLS(query1,3)>10)*(CHOOSECOLS(query1,4)<87027)))
