Forcing radio button to NO based upon select box selection

Forcing radio button to NO based upon select box selection

I'm trying to force a radio button to be selected to No based on country selection, while also disabling the ability to change it. Australia and China aren't eligible for Rush, so the radio has to default to No without the ability to change it... unless the country is changed.

  2. <select id="country" name="country" class="form-control" required="required">
  3. <option value="" selected>-- Please Select --</option>
  4. <option value="AU">Australia</option>
  5. <option value="BR">Brazil</option>
  6. <option value="CA">Canada</option>
  7. <option value="CN">China</option>
  8. <option value="FR">France</option>
  9. <option value="DE">Germany</option>
  10. <option value="ES">Spain</option>
  11. <option value="GB">United Kingdom</option>
  12. <option value="US">United States</option>
  13. </select>

  16. <label class="radioyn"><input type="radio" name="rush" value="Yes" required="">Yes</label>
  17. <label class="radioyn"><input type="radio" name="rush" value="No">No</label>
