Why repeated "require" statements in mod_escal?

[mjweissman.org]

I had been having some PHP timeout problems with our mambo site, and our ISP said the timeouts were caused (in part) by the repeated PHP "require" statements in mod_escal:

<?php $CSS=1; require ("modules/calendar/calendar.php"); ?>
<?php // $OL=1; require ("modules/calendar/calendar.php"); ?>

<table align="center">
<tr><td>
<?php require ("modules/calendar/calendar.php"); ?>

I wonder if someone can explain what exactly is going on there. As above, I more or less get what I need. If I set CSS=0, the mini-calendar is actually shown twice on the home page; if I set CSS=0 I need to comment out the immediately following require statement to get normal behavior.

The CSS statement simply loads the CSS for the calendar.

The last require actually prints the calendar. Do you have any problems viewing the calendar/demo.php page?
