    No. 19 last appered 3 games ago and then 6 games ago
    No. 29 last appered 7 games ago
    No. 33 last appered 3 games ago and then 6 games ago
    No. 37 last appered 3 games ago and then 6 games ago

  • It woudlbe easier if you showed us your expected outcomes, and easier still if you attached a sample workbook with source data and expected outcomes added manually.

  • In J2:


    =IFERROR(INDEX($A$2:$A$26,SMALL(IF($C$2:$G$26=$I2,ROW($C$2:$G$26)),COLUMNS($J2:J2))-1),"")


    ... confirmed by pressing CTRL+SHIFT+ENTER to activate the array, not just ENTER. You will know the array is active when you see curly braces { } appear around your formula. If you do not CTRL+SHIFT+ENTER you will get an error or a clearly incorrect answer. Once confirmed, drag copy across and down.
