Check box without overwriting formula ?

Sum81

Hi,

 

Here's the problem I'm facing. For each task, I'd like the two following columns : 

- one checkbox

- one harvey ball 

Users can either update the harvey ball or check the box.

Can the box be checked :

- Automatically when harvey ball = full" (=IF([Harbey Ball]= "Full", 1, 0)

- AND manually by user, without overwriting the formula above ?

 

Thanks for your advice!

If someone manually checks the box, the formula will be overwritten, there is no way around that. If you wish to keep the formula there, I would lock the checkbox column and have people only update the harvey ball column or vice versa.
