I have a form that I use to register hours for different projects. The form has fields to fill in new data, and a subform that shows records that already exists for the chosen project. I need a button (or similar) that I can click that checks all the checkboxes for the chosen project ID I'm working on, to register them as "completed". I have a column named Passive (Yes/No) for that. Any idea how to make this happen so I don't have to click them one by one? Keep in mind that I'm not a programmer.
