Issue with formula including LARGE() + multiple criterias - excel

Question

At the moment my formula looks for a LARGE number in column D, which is greater than number in K4, however if the number in K4 is greater than the LARGEST number in col D I get an error #NUM!
=IF(AND($K$4="",$D$5=""),"Not Reported",IF(AND($K$4="",$D$5<>""),"Missing DATA",IF(AND($K$4<>"",$D$5<>""),INDEX($E$5:$E$23,MATCH((SMALL($D$5:$D$23,COUNTIF($D$5:$D$23,""&$K$4)+1)),$D$5:$D$23,0),1))*1-$K$4/SUM(LARGE($D$5:$D$23,COUNTIF($D$5:$D$23,">"&$K$4)+1)+SMALL($D$5:$D$23,COUNTIF($D$5:$D$23,""&$K$4)+1))))+INDEX($E$5:$E$23,MATCH("P98",$A$5:$A$23,0)))))
Can you advise how to alter it, so if the above occurs, instead of taking the number from K4 into consideration, simply replace it with whatever the LARGEST number in col D is and finish the rest of calculations [embedded in the formula]. Appreciate your help.
PS. IFERROR is not an option (it doesn't solve this)

Answer 1

I can't give an exact answer since I don't have exact detail about what you're trying to do, however it sounds like you want to do something like this:
=max(k4, d:d)
So: If K4 is the same are bigger than the largest number in Column D, then use K4. Otherwise, use the biggest number in Column D.

Answer 2

So, this works for me:
=IF($J$4="",F27,(IF(J4>=MAX(B5:B23),(INDEX($C$5:$C$23,MATCH((SMALL($B$5:$B$23,COUNTIF($B$5:$B$23,"<"&IF(J4>MAX(B5:B23),MAX(B5:B23),J4))+1)),$B$5:$B$23,0),1))*(1-((IF(J4>MAX(B5:B23),MAX(B5:B23),J4))/SUM(LARGE($B$5:$B$23,COUNTIF($B$5:$B$23,">"&(IF(J4>MAX(B5:B23),MAX(B5:B23),J4)))+1)+SMALL($B$5:$B$23,COUNTIF($B$5:$B$23,"<"&(IF(J4>MAX(B5:B23),MAX(B5:B23),J4)))+1))))+INDEX($C$5:$C$23,MATCH("P98",$A$5:$A$23,0),1),IF(J4<=MIN(B5:B23),INDEX($C$5:$C$23,MATCH((SMALL($B$5:$B$23,COUNTIF($B$5:$B$23,">"&IF(J4<MIN(B5:B23),MIN(B5:B23),J4))+1)),$B$5:$B$23,0),1))*(1-((IF(J4<MIN(B5:B23),MIN(B5:B23),J4))/SUM(LARGE($B$5:$B$23,COUNTIF($B$5:$B$23,"<"&(IF(J4<MIN(B5:B23),MIN(B5:B23),J4)))+1)+SMALL($B$5:$B$23,COUNTIF($B$5:$B$23,">"&(IF(J4<MIN(B5:B23),MIN(B5:B23),J4)))+1))))+INDEX($C$5:$C$23,MATCH("P98",$A$5:$A$23,0),1),(INDEX($C$5:$C$23,MATCH((SMALL($B$5:$B$23,COUNTIF($B$5:$B$23,"<"&$J$4)+1)),$B$5:$B$23,0),1))*(1-($J$4/SUM(LARGE($B$5:$B$23,COUNTIF($B$5:$B$23,">"&$J$4)+1)+SMALL($B$5:$B$23,COUNTIF($B$5:$B$23,"<"&$J$4)+1))))+INDEX($C$5:$C$23,MATCH("P98",$A$5:$A$23,0),1)))))
I had to also hedge against the K4 (or J4) value being <MIN(B5:B23)
