If its a date in a table header than match isnt going to match it. It will see the header as text. Something like this might work:
=MATCH(TRUE,INDEX(--('Date Tracker'!$E$5:$DT$5)=J6,0),0)
That's the formula:
{=MATCH(J6,'Date Tracker'!$E$5:$DT$5,0)}
I tried to specify a date in J6 and it still does not find it.
I made sure that 'Date Tracker'!$E$5:$DT$5 and J6 are in date format.
This match formula as is does not require control+shift+enter.
In case 'Date Tracker'!$E$5:$DT$5 consists of text numbers: Control+shift+enter, not just enter...
=MATCH(J6,'Date Tracker'!$E$5:$DT$5+0,0)
Does this succeed?
Nope, it doesn't work
What does it do, return #N/A or a wrong result?
Care to post E5:K5 from Date Tracker'!$E$5:$DT$5?
Ah it works when inserted as array formula!
Btw, you do +0 to convert it into text? Or how exactly does it work?
Thanks
