@Lederp Yes so I'm using the Wizard for creating record of SheetResource, my code is structured like the documentation example https://filamentphp.com/docs/3.x/panels/resources/creating-records#using-a-wizard(getSteps() into CreateSheet class and function for every section of the form in my SheetResource class and called into the getSteps() class)
So for the $get, I have in the first step of the Wizard a field named 'days' which is a number of days (for example : 4), and in the next step I have a repeater named 'schedule'. So what I try to achieve is to set the number of repeater instance by default with the days value
