# "=IF" with more than 64 levels of nesting

I have the formula but how do I use the "Lookup" formula so I can have more than 64 levels of nesting?
I tried and I keep getting an error when I try to use the "Lookup" formula

The formula is:

=IF(B:B=Inventory!A2,Inventory!B2:D2,IF(B:B=Inventory!A3,Inventory!B3:D3,IF(B:B=Inventory!A4,Inventory!B4:D4,IF(B:B=Inventory!A5,Inventory!B5:D5,IF(B:B=Inventory!A6,Inventory!B6:D6,IF(B:B=Inventory!A7,Inventory!B7:D7,IF(B:B=Inventory!A8,Inventory!B8:D8,IF(B:B=Inventory!A9,Inventory!B9:D9,IF(B:B=Inventory!A10,Inventory!B10:D10,IF(B:B=Inventory!A11,Inventory!B11:D11,IF(B:B=Inventory!A12,Inventory!B12:D12,IF(B:B=Inventory!A13,Inventory!B13:D13,IF(B:B=Inventory!A14,Inventory!B14:D14,IF(B:B=Inventory!A15,Inventory!B15:D15,IF(B:B=Inventory!A16,Inventory!B16:D16,IF(B:B=Inventory!A17,Inventory!B17:D17,IF(B:B=Inventory!A18,Inventory!B18:D18,IF(B:B=Inventory!A19,Inventory!B19:D19,IF(B:B=Inventory!A20,Inventory!B20:D20,IF(B:B=Inventory!A21,Inventory!B21:D21,IF(B:B=Inventory!A22,Inventory!B22:D22,IF(B:B=Inventory!A23,Inventory!B23:D23,IF(B:B=Inventory!A24,Inventory!B24:D24,IF(B:B=Inventory!A25,Inventory!B25:D25,IF(B:B=Inventory!A26,Inventory!B26:D26,IF(B:B=Inventory!A27,Inventory!B27:D27,IF(B:B=Inventory!A28,Inventory!B28:D28,IF(B:B=Inventory!A29,Inventory!B29:D29,IF(B:B=Inventory!A30,Inventory!B30:D30,IF(B:B=Inventory!A31,Inventory!B31:D31,IF(B:B=Inventory!A32,Inventory!B32:D32,IF(B:B=Inventory!A33,Inventory!B33:D33,IF(B:B=Inventory!A34,Inventory!B34:D34,IF(B:B=Inventory!A35,Inventory!B35:D35,IF(B:B=Inventory!A36,Inventory!B36:D36,IF(B:B=Inventory!A37,Inventory!B37:D37,IF(B:B=Inventory!A38,Inventory!B38:D38,IF(B:B=Inventory!A39,Inventory!B39:D39,IF(B:B=Inventory!A40,Inventory!B40:D40,IF(B:B=Inventory!A41,Inventory!B41:D41,IF(B:B=Inventory!A42,Inventory!B42:D42,IF(B:B=Inventory!A43,Inventory!B43:D43,IF(B:B=Inventory!A44,Inventory!B44:D44,IF(B:B=Inventory!A45,Inventory!B45:D45,IF(B:B=Inventory!A46,Inventory!B46:D46,IF(B:B=Inventory!A47,Inventory!B47:D47,IF(B:B=Inventory!A48,Inventory!B48:D48,IF(B:B=Inventory!A49,Inventory!B49:D49,IF(B:B=Inventory!A50,Inventory!B50:D50,IF(B:B=Inventory!A51,Inventory!B51:D51,IF(B:B=Inventory!A52,Inventory!B52:D52,IF(B:B=Inventory!A53,Inventory!B53:D53,IF(B:B=Inventory!A54,Inventory!B54:D54,IF(B:B=Inventory!A55,Inventory!B55:D55,IF(B:B=Inventory!A56,Inventory!B56:D56,IF(B:B=Inventory!A57,Inventory!B57:D57,IF(B:B=Inventory!A58,Inventory!B58:D58,IF(B:B=Inventory!A59,Inventory!B59:D59,IF(B:B=Inventory!A60,Inventory!B60:D60,IF(B:B=Inventory!A61,Inventory!B61:D61,IF(B:B=Inventory!A62,Inventory!B62:D62,IF(B:B=Inventory!A63,Inventory!B63:D63,IF(B:B=Inventory!A64,Inventory!B64:D64,IF(B:B=Inventory!A65,Inventory!B65:D65,IF(B:B=Inventory!A66,Inventory!B66:D66)))))))))))))))))))))))))))))))))))))))))))))))))))))))))))))))))

Why does 9 mean SUM in SUBTOTAL?
It is because Sum is the 9th alphabetically in Average, Count, CountA, Max, Min, Product, StDev.S, StDev.P, Sum, VAR.S, VAR.P.

Looks like you should rethink your approach.
Maybe show here in a concise manner what you want to accomplish and there will be someone with a better approach.

Welcome to the forum!

Clearly there is a better way to do it than a huge formula. If your Inventory sheet looks like this:

Book1
ABCD
1CodeVal1Val2Val3
2a1611
3b2712
4c3813
5d4914
6e51015
7
Inventory

You can do something like this:

Cell Formulas
RangeFormula
C2:E7C2=INDEX(Inventory!\$B\$2:\$D\$66,MATCH(B2,Inventory!\$A\$2:\$A\$66,0),0)
Press CTRL+SHIFT+ENTER to enter array formulas.

Much shorter formula. There are a couple of interesting points with your original formula. You're using B:B=Inventory!A2, which seems to indicate you're using implicit intersection. That has been reimagined in newer versions of Excel, and should be avoided. I just used the B2 value for matching. Then you're returning a 3-column result, so I put displayed that by selecting the 3 columns and using Control+Shift+Enter.

If this does not reflect what you want, please try to explain a bit clearer. If you use the XL2BB tool, like I just did, it's much easier to explain what you want. You can download it from my signature, or the response box. It's easy to download, install, and use.
