Hello,
In colum a I have dates. In colum H I have summarized data in table. I want to keep from having to enter data everytime.
Ie... h9 has a value of a date, I want h10 h11 and so on to display previous h+8 only if colum a has dates according.....
H9 is 12/7/18.
H10 needs to be 12/15/18 only if a2:a100 has a date on or after h9+8.
I tried =if(a2:a100>=h9+8;h9+8;"") but getting blank results

Hi,
Code: Select all   Expand viewCollapse view
=IF(COUNTIF($A$2:$A$100;">="&(H9+8));H9+8;"")

Then the H9 has a zero value in YOUR file. For example it contains a textual data with zero value.

Got it to work when h9 has date... but when fill down if h10 is blank then h11 thru h61fills with bad data... so on and so forth... shouldn't the others be blank? Yes It uses same formula except h9 become h10+8, h11+8... and so on. If h10 is blank then so should h11.... and so on right?

Try the
=IF(ISBLANK(H9;"";your_condition))
formula

Your_condition? Would that be the part? Or start with if(countif?

508
Error: Pair missing
Missing bracket, for example, closing brackets, but no opening brackets

Count your brackets. Use your F1- Help to find the meaning of the error messages.

You need three closeing brackets at the end of the formula. One for the IF(), ant another for ISBLANK() and the third for your condition.

see the dates in h11,h12,h13 are off but h10 is right

H11 is off due to the fact that the formula for calculating the date refers to H10, which is blank, thus returning the equivalent of a 0 value for other calculations.
H12 and H13 have similar problems, but they can all be traced back to the fact that you have a blank, thus a 0 value, in H10.

Correct. That's my issue. I would like the others be blank if the one before is blank

This implies a loss of information.

I thought that's the reason for the if,countif code. It only supposed to calculate if there's value in row above. Otherwise leave blank

Try
Code: Select all   Expand viewCollapse view
=if(isnum(H9);H9+8;"")

instead of the code you're currently using

There are many functions to examine the content of a cell:

ISBLANK()
ISNUMBER()
ISNA()
ISERROR()
ISERR()
ISEVEN()
ISODD()
...and more.

Read the HELP, and use the function what you need for your task.
