Option Buttons for Page Setup change when selected

Hi guys

I have 4 option buttons on my Worksheet they are as follows:

However when i change the page size buttons 1 & 2 it also changes the orientation buttons 3 & 4. I'd like these buttons to remain 'on' or 'off' so that the user knows exactly how the print is going to function.

any ideas on solving this?

Thanks heaps guys
