=IFERROR(AVERAGEIFS('Journal Input'!$AO$4:$AO$480,'Journal Input'!$O$4:$O$480,">="&F10,'Journal Input'!$O$4:$O$480,"<="&EOMONTH(F10,0)),"N/A")
This formula works but I need multiple average ranges added to this equation. My first average data range is AO but I have others in different columns (BB, BM, etc.) I would like to average along w/ AO. My multiple criteria's cover the beginning and end of the month F10. Perhaps an array is necessary? Any help is appreciated. Thanks Mike Link to picture example here
