Let me see if I can understand your pos after spending some time reading it over and over:
You have a CLV that has items and each item is populated with two B4XSwitches. One B4XSwitchACC1 and the other B4XSwitchACC2. You want to scroll to any CLV panel and click on either B4XSwitches to change its state (value) from True to False or vice versa. You want the B4XSwitch_ValueChanged to tell you which of the two was clicked (1 or 2) and what the value is for the one you clicked (True or False). If this is what you want, I can help you. If not, it is best to post your code/project.
