All good options! Just to give you some more options on this one @Hangman
You could create a formula column that adds up how many columns have a value over zero (i.e. SUM(IF({columnX}>0,“1”),IF({columnY}>0,“1”,…)). You could then view that to know how many columns have been filled in with data (if the data is numerical).
Beyond that, you could create a formula that if that if the sum of a column equals a certain number (i.e. all the columns have been filled in with data), it returns back a phrase like “all data complete,” or whatever works for you.
Let me know if you want to hop on a Zoom call about this. My email is julie@lucidday.com.
