包含多个选项的if-then语句

Question

I have been working on an IF statement where there are multiple answers but I can't seem to get the formula to work. The If statement is going to look at two columns of data and should pull back the first NUMBER. Sometimes the first column will say "#N/AN/A" in which case the formula should look to the second column and pull that NUMBER. If both columns say "#N/AN/A" then I would like the answer to be "NR".

In another scenario I will have three columns of data. I would like the formula to pick up the first number in the columns no matter what follows. Again, if all three columns say "#N/AN/A" I would like the answer to be "NR".

I will attach two examples of what I am talking about. Here is the formula I have now but I can't seem to get it to work:

=IF(ISBLANK(B3),"",IF(D3="#N/A N/A",$D3,$D4))

Unfortunately, this formula isn't taking into account if D3 is actually a number. It also doesn't account for if both D3 and D4 are "#N/AN/A".

Any help would be greatly appreciated.

Thanks,

Here is the example :

Answer 1

This allows the use of many columns without the need for multiple nested ifs.

It will return the first column that is not #N/AN/A :

=IFERROR(INDEX(3:3,,AGGREGATE(15,6,COLUMN(D3:E3)/(D3:E3<>"#N/A N/A"),1)),"NR")

So to do more columns simple change both the D3:E3 to the range desired. The 3:3 should match the row being searched.

Answer 2

You can check each cell (from left to right) and return the first instance of a numerical value using a combination of IF & ISNUMBER

---

Checking 2 Columns

=IF(ISNUMBER(D3),D3,IF(ISNUMBER(E3),E3,"NR"))

---

Checking 3 Columns

=IF(ISNUMBER(D3),D3,IF(ISNUMBER(E3),E3,IF(ISNUMBER(F3),F3,"NR")))
