[jQuery] getting 'undefined' using jquery.expander

[jQuery] getting 'undefined' using jquery.expander


Hi All,
This is my first post and am VERY new to jquery (but love it!), so
please forgive me for any violations of protocol.
I'm using jquery.expander with the following code:
$(document).ready(function() {
        $('ul.expander span').expander({
            slicePoint: 0,
            expandEffect: 'fadeIn'
            });
        });
to make the embedded ul (within the span) in the following code hide
and show:
<ul class="expander">
<li>Apply the right information and resources in an organized and
consistent manner.</li>
<li>Assess practice readiness and optimize for care management. </
li>
<li>Promote improved patient care by:
<span>
<ul>
<li>Building a team that values the benefits of new
and efficient processes.</li>
<li>Implementing workflows that target the needs of
chronic care populations.</li>
<li>Enhancing patients' confidence in managing their
health</li>
<li>Embracing Clinical Decision Support</li>
</ul>
</span>
</li>
</ul>
It works fine. However, the text ''read more...", rather than
disappearing as it should, is replaced by the 'undeclared'.
Any ideas why this would happen??
Thanks!
