how to leave existing data after IF ELSE function

[ben-t]

I'm extracting data off a sharepoint list where the status change of each issue is updated as the issues are fixed. 

I'm trying to keep a daily record of the count of each status,

Is there a way for it to count IF the date is today, ELSE leave the existing data? 

thanks

@ben-t , What column you want leave put that in else

example 

if([Date] = today() , counrows(filter(<Your code>)), [Column 1])

[ben-t]

I want to keep the data in the same column that was written the day before. 

the code that i've written only writes to today's date, then for every other date it wipes the values. 

i tried selecting the same [completed] column in else, but there seems to be an error. 

If not, is it possible to write this row of data to a new sharepoint list?
