banner managment ( zone code problem)

i have installed the banner managment and it is working fine.

i've decided to place my banners in the calander area so i've used the archive_calendar.tpl to place my zone codes. it works for one zone perfectly but when i add another code it does not appear, only first zone is there.

the archive_calendar.tpl looks like this:

<vte:load module="box_banners" search_zone_id="1" />
<vte:load module="box_banners" search_zone_id="2" />
<vte:load module="box_banners" search_zone_id="3" />


what might be the mistake am doing,

please advice

warmest regards,
