Thanks @vletm but when I change the date the result doesn't change, its possible without column helper?
The rule is if there is the number on range B2:F7 within 2 dates on columns header then return row header, hope its clear nowKenshin
Seems You didn't know how did You get that or those results?
Because that mystery B12 - I used below cell to get one sample result - as You noticed.
Many things could be possible, but without clear rules ...
