Assuming the col headers in B1:E1 are amended
to be just numbers, eg: "1" instead of "Wk1" (drop the "Wk"),
you could then place this expression in F2:
=SUBSTITUTE(TRIM(IF(B225,B$1," ")&IF(C225,C$1," ")&IF(D225,D$1,"
")&IF(E225,E$1," "))," ",",")
and copy F2 down to return exactly the results that you seek
