How to INDEX from Sheet2 and Sheet3 to find value for Sheet1

Question

On Sheet1 I have data based on an Order # and I want the Multiplier that is associated with it. The Multiplier is on both Sheet2 and Sheet3 with the Order #, but the Order #'s and Multipliers associated always change spots in the same column every day so I cannot just copy and paste. I want the Multipler in line with the correct Order # on Sheet1. I attached pictures to help visualize, but the formula I have so far is just for getting Sheet2 Multipliers as I forgot about the 3rd sheet.

Answer 1

堆叠两者，如果Sheet2失败，则将查找传递给Sheet3。

=iferror(iferror(index(sheet2!d:d, match(a2, sheet2!b:b, 0)), index(sheet3!d:d, match(a2, sheet3!b:b, 0))), text(,))

Answer 2

How about you use a vuplook with iferror. Something like this column D:

= iferror(vuplook(A2;Sheet2!B2:D8;4;true);vuplook(A2;Sheet3!B2:D8;4;true))

That should get the multiplier from sheet two, and if it is not here it should return it from sheet3.
