Hi,

  I did the calendar tutorial, and once I upload to the server, it doesn't display the calender at all, only the header tag. What am I doing wrong ???

Here is the link:

[url=http://www.pacificcollege.edu/PHP_TEST/calender.php]http://www.pacificcollege.edu/PHP_TEST/calender.php[/url]

and here is the php code:

<html>
<head>
<title>PHP CALENDER</title>
<style type="text/css">
<!--
.table.calender { border: 1px solid #000000; border-collapse: collapse; color: #000000; background: #FFFFFF;}
.td.today { border: 1px solid white; color:#000000; background: #EFEFEF; font-weight: bold;}
.td.nomonthdays { border: 1px solid white; color: #000000; background: #EFEFEFEF;}
-->
</style>

</head>

Ok, I did what you suggested here is the link:

[url=http://www.pacificcollege.edu/PHP_TEST/calender.php]http://www.pacificcollege.edu/PHP_TEST/calender.php[/url]

But, I'm interning for this company, so I'm just practicing on their servver, so I don't want to mess with their confiquration, and I don't know if the "error reporting level is in your php.ini file or if the display errors is turned off"

I'm just a beginner at this, and I would like to practice on the scripting. so that's why I'm doing the tutorials on this site to gain some understanding.

There is a special forum for help with PHPFreaks tutorials as well as a Third-Party Scripts forum.  All of this is outlined in the guidelines.

Well, I'm going to take a break from this, been at it all day, and I still don't see the calendar, anyways I took it down, so it wont display. Anyways, here is my other question before I leave. In order for me to have this work, I have to install php.ini and where do I install at in my machine or the server? Like I said I'm totally new at this, and if I can have someone guide me thru this, I would greatly appreciate it! Anyways, thanks guys for trying to help me out with this, you guys ROCK! Now, off to my Kung-Fu lesson.
