select multiple checkboses in matlab - matlab

Question

I have a gui with nine checkbox in the following code i can select only one of each but what i wanted to add is if the NormeEm checkbox is selected i want to select another checkbox, which i tried to set up at the end of the code by using a switch and 2 cases so that only another one checkbox can be selected but it won't show and it doesn't give me an error code.

If i could have some help to figure out what's wrong in my code it would help me a lot
