gcal events plugin

hi all,

i am displaying the google calendar using the google calendar events ver 2.1.6.1 . I am able to see only one month in total. The navigation key to check the next month or previous month doesnt work. Please see the html code in the page I am using

[gcal id=”12900″ interval=”events” interval_count=”500″ display=”grid” paging=”true”]

please check the calendar here

i have added a feed to gcal events and by default the following code comes by default which I dont understand.

<div class=”gce-list-event gce-tooltip-event”>[event-title]</div>
<div><span>Starts:</span> [start-time]</div>
<div><span>Ends:</span> [end-date] – [end-time]</div>
[if-location]<div><span>Location:</span> [location]</div>[/if-location]
[if-description]<div><span>Description:</span> [description]</div>[/if-description]
<div>[link newwindow=”true”]More details…[/link]</div>
