How to CONCATENATE with different criteria with changing data.

[phamc]

So I am trying to find the right formula using sumifs to concatenate days into one line in a workbook. Based on the task description and the Name i'm trying to come up with a formula that will give me the end result of what is in Column "J".

The work book has multiple names and task description. Overall I hitting a wall to come up with a formula that will give me all the number in Column "C" if it has the same name and task description. This data will then be filtered using the Pivot table so the repetition of the same info will be filter out.

Maybe:

J2 ="Dec "&TEXTJOIN(",",TRUE,IF($F$2:$F$12=F2,IF($I$2:$I$12=I2,$C$2:$C$12,""),""))

Copied down
