So i used this method ( check group and check) once then tried to use it again and when and checks won't come up where the objects are already present in the list. for example. you have a list of all colors and i have a list of blue and green. when i look at the check box, blue and green should be selected. but they are not. nothing is. can someone tell me why this isn't working. what ties the check to an object? what is used to determine what object is in the list already and what is not.?
