@oceancloud I'm still relatively new to SS, so there may be a better option. But this is how I'd approach it: Is the Change To value something static that can be added to the Script? Or is it something more dynamic that you need to prompt the user for after the button is pressed? If static: I'd create a client script with a function that get's the current record. Then loops through the item sublist and sets the desired field to that static value. If dynamic, I'd do the same, however I'd first write in a JavaScript prompt, which will accept a value from the user. Then, when the user clicks the confirm button it again loops through the item list, but this time uses the value it got from the user as the new field value.... As for the button, I'd create a script record for this script that has button parameters set (give it any label and point the function field to the function in your script). Then I'd set the deployment to 'edit'.
