i am trying to count how many coils have at least 1 piece of missing test data. The report I pull will show all the information and the missing test data by type. I have created a set up to pull the names of the missing data into one column called missing test data.
I also have a month/date column. I am trying to calculate the number of coils per month that have missing data.
On a separate sheet I have a month data column and have tried to do sumif and countif and keep getting incorrect argument set.
formula:
=COUNTIF({month-year}, [Month-Year]@row, {missing})
Initial sheet:
count sheet:
Ultimately I am trying to set it up so I can chart the number of coils per month, # of missing test pieces per month, missing test pieces by count (pareto), but can't get past the first one.
on the initial sheet the missing test data column is a column formula, not sure if that has anything to do with it.
I have also tried sumif, count, sum all with same issue.
