I have a radio button with Yes/No options. If the user selects 'Yes', a group of questions and a button are made visible. If the user wants to add an additional group of questions they are to click on the button that was just made visible. The additional group of questions are in a subform that will repeat if the user clicks on the button. If the user changes their mind from 'Yes' to 'No', I need to have the subforms that were added removed. How can all instances of repeating subform be removed by selecting the 'No' option?
