    Hi,

    I've got a serie of radio options in a form, if the last option gets
    selected I want it to Enable a different (text) form field.
    Is it possible to monitor if a radio button in a form get's unselected
    instead of supplying the same piece of JavaScript code for each other
    radio option?

    Situation:

    <fieldset>
    <legend><b>7. Are you still alive?</b></legend>
    <input type="radio" name="q7" value="yes"
    onclick="document.surveyform.nocodec7.disabled=true;" />Yes<br />
    <input type="radio" name="q7" value="abit"
    onclick="document.surveyform.nocodec7.disabled=true;" />A little bit<br />
    <input type="radio" name="q7" value="no"
    onclick="document.surveyform.nocodec7.disabled=false;" />No, because:
    <input type="text" name="reason7" disabled />
    </fieldset>

    Now, in this example the text field is Disabled by default, if the
    option "No" is selected this field gets activated.
    If any of the other options are selected it will Disable the text field
    again.
    Although this is perfectly working I'm interested to know if it isn't
    just possible to execute some piece of code as soon as option "No"
    becomes deselected.
