You >>>MUST<<< use ; as the separator, not a mix of , and ; BOTH were present in the file you uploaded. I think I've removed them all.

I think this does it...

Formula:

=LET(

A,FILTER(Database!B2:U88,ISNUMBER(XMATCH(Database!A2:A88,B5:J5))),

B,VSTACK(Database!B1:U1,A),

C,FILTER(B,BYCOL(B,LAMBDA(z,ISNA(XMATCH("No",z))))),

D,TAKE(C,1),

E,TRANSPOSE(FILTER(D,D<>0)),

F,DROP(C,1,1),

G,BYCOL(F,LAMBDA(x,TEXTJOIN(";",,x))),

H,TRANSPOSE(FILTER(G,(LEFT(G,1)<>"Y")*(G<>""))),

I,IFERROR(DROP(REDUCE("",H,LAMBDA(x,y,VSTACK(x,--UNIQUE(TEXTSPLIT(y,";"),1)))),1),""),

J,BYROW(I,LAMBDA(x,TEXTJOIN(", ",,IFERROR(VLOOKUP(x,Database!X4:Y14,2,FALSE),"")))),

BYROW(HSTACK(E,J),LAMBDA(X,TEXTJOIN(", ",,X))))

It's all broken up into baby steps to make it easy (I hope) to unpick if needed!!
