Complex combination of IF/AND Formula (Help Needed)

[dmxcasper2]

Problem Statement:
I am having difficulty creating a formula that will take multiple AND and IF criteria into calculation based on today's date. Please see below for (4) logic statements that I have been trying to incorporate into a single formula string.

Column E is the output. (Where the formula would reside)

Formula is needed based on the following logic statements:

1. If there is no date in Column A, then default to "blank" in Column E
2. If there is a non-date attribute (example: "TBD", or "TBA") in Column A, then default to "blank" in column E
3. If there is a date in Column B, then subtract it from MAX of Column C and D.
4. If there is a date in Column A and Column B is blank, take the MAX date of Column C and D and subtract it from today's date

Any help is appreciate it.
I can't find a good source online to explain/teach the logic behind creating these AND and IF combinations.

How about
=IF(OR(A2="",ISTEXT(A2)),"blank",IF(B2<>"",MAX(C2:D2)-B2,TODAY()-MAX(C2:D2)))

Hi,

Another way to write that formula:

Book1
	A	B	C	D	E
2
3	TBD
4	9/29/2018	10/3/2018	10/2/2018	10/4/2018	1
5	9/29/2018		10/2/2018	10/30/2018	45
Sheet398

Cell Formulas
Range	Formula
E2	=IF(N(A2)=0,"",IF(B2,MAX(C2,D2)-B2,TODAY()-MAX(C2,D2)))

Formula in E2 copied down.

Thanx Fluff and jtakw. Both formulas work as intended.

Is is possible to also integrate the following logic statements to both of your existing formulas?

If Column A has a date and Column B is blank, and also if Column C or D is blank then equal "blank"
If Column A & Column B has a date, and also if Column C or D is blank then equal "blank"

See if this does what you describe:

Book1
	A	B	C	D	E
2
3	TBD
4	9/28/2018	10/2/2018
5	9/29/2018	10/3/2018	10/2/2018	10/4/2018	1
6	9/28/2018		10/3/2018
7	9/29/2018		10/2/2018	10/30/2018	45

jtakw,

I used the above formula and dissecting the data, I found couple of calculation issues based on the below logic satements

1. If there is no date in Column A, then default to "blank" in Column E
2. If there is a non-date attribute (example: "TBD", or "TBA") in Column A, then default to "blank" in column E
3. If there is a date in Column B, then subtract it from MAX of Column C and D.
4. If there is a date in Column A and Column B is blank, take the MAX date of Column C and D and subtract it from today's date
5. If Column A has a date and Column B is blank, and also if Column C or D is blank then equal "blank"
6. If Column A & Column B has a date, and also if Column C or D is blank then equal "blank"

In Both your Post # 4 and Post # 6 above, your written description says Either C OR D is blank, then return Blank, but your sample in Post # 6 shows when Both are blank, then return Blank.

Try this version:

Book1
	A	B	C	D	E
7	10/2/2018	10/10/2018	10/8/2018		2
8	10/2/2018	10/16/2018	10/8/2018		8
9	10/4/2018	10/17/2018	10/8/2018		9
10	10/16/2018	10/25/2018	10/19/2018	10/26/2018	-1
11	10/21/2018	11/1/2018	10/26/2018	10/30/2018	2
12	11/1/2018	11/2/2018	11/15/2018		-13

BTW: it would be helpful if you can upload a table rather than a picture, so that helpers can copy and paste your data for testing.
