I have a long formula that I'm trying to modify:

{=IF(OR(I3TODAY(),I3=""),"",SUMPRODUCT((Client_Da ta!$A$3:$A$4000<=$B3)*((Client_Data!$N$3:$N$4000=" ")+(Client_Data!$N$3:$N$4000=$B3))*(Client_Data!$ K$3:$K$4000=K$2)))}

Row 2 includes headers and this formula pulls data from the Client_Data
sheet which matches the K header. What I'm trying to do is to rewrite this
formula so that it doesn't look at the header's text but can be any text
found on the sheet.

I'm looking for the wildcard character to say "any text found in matching
cells". My guess is, "*", but when I enter the formula:

{=IF(OR(I3TODAY(),I3=""),"",SUMPRODUCT((Client_Da ta!$A$3:$A$4000<=$B3)*((Client_Data!$N$3:$N$4000=" ")+(Client_Data!$N$3:$N$4000=$B3))*(Client_Data!$ K$3:$K$4000="*")))}

It doesn't work the way it should. Can someone please help me exchange the
K$2 entry please??? Seems simple but it's eluding me.

Thanks in advance!
