Hi,
Is the “Confirm Bid” button binded to a collection?
If you wish to have a certain condition before adding a record to the collection, you would need to insert the record using code instead of the editor itself. You should create an onClick button to the “Confirm Bid” button, use if statement to check if the value inserted by the user is higher than what is already there, if so- insert the record using the insert function . Otherwise, you can display a message with explanation to the user.
I hope it’s clear.
Best,
Tal.
