Display MoreFurther to my posted formula in Post #.2,
Should you wanted to return multiple result in respect of the multiple criteria, you need TEXTJOIN function of which available in Office 365 or above.
Then,
In "Map" sheet F2, array formula (confirm pressing Ctrl+Shift+Enter instead of just Enter) copied down :
=IF($G2="Y",TEXTJOIN(", ",1,INDEX(Lookup!$D$2:$G$52,N(IF(1,MATCH(FILTERXML("<a><b>"&SUBSTITUTE(B2,",","</b><b>")&"</b></a>","//b"),Lookup!$C$2:$C$56,0))),MATCH(C2,Lookup!$D$1:$G$1,0))),"")
and,
Trailing space in B12 should be removed
Regards
Thanks Bosco_yip. Unfortunately I only have Office Pro Plus 2016, but your first formula worked wonders for me.
Appreciate the help Sir
