Working with JS and checkboxes

Hello,

I am currently working with a form that has several check boxes for a mutually exclusive checkboxes for a row series. Based on the check box selected, a corresponding text box will be populated with the applicable data (done using javascript). Also, when a certain option is checked, there are other options down below in the order guide that need to be checked simultaneously. I have accomplished this, but now I cannot figure out how to have check boxes populate simultaneously, but then if I check a different box in one of the previously automated series, that it will uncheck the other check box in the series automatically. I have searched and searched for an answer, but cannot find the solution. Please help!
