Hi Kal.
Just one thing that i saw: you talked about "radiobutton" component but in code you've used "mobilecheckbox_18" name that's apparently belongs to the "checkbox" component.
Anyway.
In case if you need to get value from certain radiobutton item you can use following code:
pre
//Note: "mobileradiobutton_23" is your radiobutton item name.
Apperyio("mobileradiobutton_23").find('input[type="radio"]').val();
/pre
In case if you need to get value from certain checkbox item you can use following code:
pre
//Note: "mobilecheckbox_28" is your checkbox item name.
Apperyio("mobilecheckbox_28").find('input[type="checkbox"]').val();
/pre
Regards.
