Email only if anything has changed

I am sharing our data with another research team using a totally different product altogether.

Not in a position to encourage them to move and consolidate to one product (ours of course :slight_smile: )

So whenever certain fields change I generate an email to them advising of the change.

BUT that means generating rule after rule for specific field changes. Yes it’s nice I can color the change and highlight it but in some cases there may be 2 or 3 changes in a single session before it is submitted.

SO what I want to achieve is 'HAS ANYTHING CHANGED IN THIS SESSION ?"
YES generate an email
NO dont generate anything

THE IMPLEMENTATION IS ON A FORM WHICH HAS AN UPDATE BUTTON
I would like to have them only use the button for that purpose

But for some reason I cannot get trigger an action option for the FORM nor control over the standard submit button other than in the stgandard functions which doesnt allow much function to be built in.

I would like to do an EXIT button (other than the X top right corner) for users to back out of the screen without using the update button

Any ideas ?
