Dear Sir, Please help me with a formula that could help me know the number of containers loaded in Jan only, Feb only, March only, for all the agencies and the number of containers loaded by these same agencies within Jan-Feb, Jan-Mar, Jan-Apr, Jan-May, Jan-June, etc. Please bear in mind that the list will keep on being updated, so the reflections must happen when the sheet is updated. I have attache the file. Thank You.
