The only range that holds text values is 'Density Chart'!A3:A9427)
The other two are numerical values. I put in the -- as you stated below,
still getting the error.

If this range holds any text values it will return a value error,

'Density Chart'!D3:D9427

text values can be blanks from formulas like "" or plain text

you can rewrite it as


=SUMPRODUCT(--('Density Chart'!A3:A9427=B3),--('Density
Chart'!B3:B9427=B4),'Density Chart'!D3:D9427)


that will ignore text or fix the txt values in that range

Received help with this one before (see Excel Formula - 5/3/2006) and now
the
formula works great for the worksheet labelled "Correction Values". But
now,
almost the exactly same scenerio with a worksheet labelled "Density Chart"
but I am getting a #VALUE! error.

Are my eyes just tired and I'm missing something?
=SUMPRODUCT(('Density Chart'!A3:A9427=B3)*('Density
Chart'!B3:B9427=B4)*('Density Chart'!D3:D9427))
