You can achieve that using filter datatable activity.
read range excel sheet and store in a datatable
Filter datatable to keep the rows where filtro column equals ‘#N/D’
3)Use the filtered datatable from step 2, you will have the data as shown above, now here filter the datatable again to only keep the column Total general
Now you will only have Total general column with values where filtro column had value ‘#n/D’.
Now you can paste this datatable onto your summary sheet using write range activity.
