Nesting checkboxes hack

i've tried to nest the Checkboxes hack but it didn't quit work the way i expected... i wanted to show and hide Divs or sections depending on which checkbox is selected. Here is the Link to the website, maybe somebody can point out what i am doing wrong...

i tested the checkboxes without nesting them and they work properly...

Ps. when i inspect the Code and resize it to mobile version it works better than the Desktop version...
