[jQuery] [validate] select box and text field

[jQuery] [validate] select box and text field


I'm using the jQuery plugin: http://bassistance.de/jquery-plugins/jquery-plugin-validation/
I have a select box that needs to make a text input required if a
specific value in the select box is selected.
<select name="hfrom">
<option value="" selected>Select</option>
<option value="Referral">Referral</option>
<option value="Media"> Media</option>
<option value="Industry Conferences"> Industry Conferences</option>
<option value="Other"> Other (please specify)</option>
If they choose "OTHER", I need a text input field to be required.
I couldn't find this example in the documentation. If it's there, I'm
certain I skipped it.
Can someone help me out with this? Thanks!
