Remove required field when radio button is checked

Hi,

First of all, ulihake, thank you very much for your good support and the nice plugin. I really appreciate you helping me out.

On topic.
——————–

I have created a select field with 4 radio buttons. ( it is required )
I have created 2 drop-down lists and set them to display:none ( they are required )

When selecting radio button 1, the first drop-down is shown
When selecting radio button 2, the second drop-down is shown
When selecting radio button 3, both drop-downs are hidden
When selecting radio button 4, both drop-downs are hidden

Now, what i need is
———————

When radio 1 is selected, drop-down field 2 is removed from being required.
When radio 2 is selected, drop-down field 1 is removed from being required.
When radio 3 or 4 is selected, both drop-downs are removed from being required.

I have been trying to do this for the past 2 hours without any luck. My experience with jquery is very limited. Could you please write me a script that would do this?

P.s. Perhaps you can add this function in later updates to make your plugin even better.
