Cancale auto save on a field

Assuming your original long text field is called "Notes", you can try:
1. Create another long text field called "Text to add" or some such
2. Create a checkbox field called "Add to Notes"
3. Create an automation that will trigger when the checkbox field is ticked, and its action will be to add the text from the "Text to add" field to the "Notes" field, as well as clear the "Text to add" and checkbox field

That a great idea! thank you!

But is they any way to additionally defend the "Notes" field contact from being deleting or at least get a notification about it.
The thing is that i want users to be able to add contact freely but no to delete an existing one. 

Hmm, if you're on a paid plan you can set a field permission so that no one can modify it except an automation, which I think would do what you want? 

Actually after checking some more option i rather to just cancale the auto save, is there any way to do that?

I don't think that's possible I'm afraid

I see, I'm having a problem setting the automation you suggest, do you happen to have a guide that shows how to do something similar to that?

Ah sorry, I don't have a guide for that.  I've put it together in a base here so that you can try to replicate it though!

First this thank you very much, i'm really appraiser it.
Is the automation works for real in this base or you just want to explain the format? If it is work so i really like to view the fiels type and details.

can you please grant me permissions to see your automation? i want to replicate it on my env.

Thank you

I've done it!!!! Thanks to you!!!! you are great my friend!! thank you so much
