[jQuery] How do I... select box onclick enable other form elements?

[jQuery] How do I... select box onclick enable other form elements?


I'm fairly new to jQuery and getting on OK but this one baffles me.
I have a form with a select list with three values. One of the values
should do nothing while the other two should enable two other form
fields that have been disabled. The structure is like this:
<select id="question">
<option value="no">This</option>
<option value="yes">That</option> <-- click this to enable fields
below
<option value="yes">The other</option> <-- click this to enable
fields below
</select>
<select id="box2" disabled="disabled">
<options...>
</select>
<input type="text" id="autocomplete" disabled="disabled" />
I've tried following the manual as best as possible but I'm obviously
not doing it right =(
