Multiple IF statements in Excel

Question

How can I do this in Excel with Multiple IF statements:-

The conditions:-

Answer 1

Here is how you'd write in for say, HIJ assuming by NULL you mean the value 0 and not empty cell:

=IF(C4>0,C4,IF(B4>0,B4,D4))

In layman's terms, If C4 is greater than 0, give me C4, if it's not then tell me if B4 is greater than 0, and if it is, give me B4, otherwise, just give me D4).

Answer 2

The IF function has the following structure:

IF(logical_test, [value_if_true], [value_if_false])

You can nest further IF's in the [value_if_true] and/or [value_if_false] arguments.

In your particular case, paste this in E2 and copy-drag down:

=IF(ISERROR(C2),IF(ISERROR(B2),D2,B2),C2)

Now, this assumes that your dates are sometimes #NULL! like your question suggests, but I doubt that this is what you actually mean. Maybe you mean blank? Or some other value? If you do mean blank, then replace ISERROR with ISBLANK in the above.
