Hi Corey,
Don't worry about being new to MVD - we all were at one point!
With respect, I still think you're over-complicating things; if I understand correctly, all you're trying to do in your post is allow the user to set which temperature scale is the 'default' and then that default scale should be automatically displayed in a label on Form1.
As such, there isn't any need for comboboxes with Options1 and 2 etc, multiple checkboxes and discrete labels for whatever scale is chosen.
Have a look at the attachment as a (hopefully) more straightforward approach. Note how it is 'data driven' rather than 'code driven' - in other words, the user can change defaults, add, change and delete temperature scales etc without the programmer needing to get involved with adding new hidden labels, new checkboxes etc.
Referring back to your original post, you can do exactly the same thing with 'measurements'.
Shout out if anything's unclear.
Derek.
