DIV error, excel 2016

cell J7 is empty (zero), so you got a divided by zero error.

J7 is blank, so your formula in K7 is dividing by 0. Use this formula in K7 (and copy it down) instead:

=IF(SUM(J7)=0,"",ROUNDUP(I13/J7,0)*J7)

Select allOpen in new window

Or you can require both I13 and J7 to have values:

=IF(OR(SUM(J7)=0, SUM(I13)=0),"",ROUNDUP(I13/J7,0)*J7)

Select allOpen in new window

I assume the formula in cell K13 is a SUM formula. If so, it will return 0 once you fix the formula in cell K7. If the formula in K13 tests whether the SUM is 0 and returns an empty string (looks like a blank) if so, it will still be fixed when you fix the formula in cell K7.

so does that mean i must have a value in cell j7 at all times otherwise the formula will show a 'DIV' error always?
- also, can the formula in k13 have an if statement that if there is zero or nothing in j7, then show nothing otherwise sum k7 to k12?

Yup, since your formula use the value of J7 for division calculation.

also, can the formula in k13 have an if statement that if there is zero or nothing in j7, then show nothing otherwise sum k7 to k12?                                  

see if below is the one you looking for?

=IF(SUM(I13)=0,"",ROUNDUP(I13/ IF(J7=0,1,J7),0)*IF(J7=0,1,J7))

Select allOpen in new window

or:

=IF(SUM(I13)=0,"",IF(J7=0,ROUNDUP(I13,0),ROUNDUP(I13/J7,0)*J7))

Frank,
The problems in column L are likely very similar to those in column K. If you have difficulty getting the right formulas for L7:L13, please post your workbook.

hi brad, yes your solution k13 & k14 have worked as in it now shows nothing in these cells if J7 is blank.
- would i use the same "iferror" formula for k7?

thankyou experts for helping me with my ifstatements that have cleaned up my worksheet..
