I need a formula in Column B that will look for duplicate INCIDENTNUMBER from column A and then put them in order based on Response times in Column C. Example: there are three incident numbers "150013" in column A. In column B, I need to see the order based from lowest response time to highest response time from column C. If there is no duplicate then just want a "1" in column B
INCIDENTNUMBER Unit in order Response
1500001 [tt][tt][tt][tt][/tt][/tt][/tt][/tt][tt][/tt] 1 0:17:46
