Calendar 3.0 -add/edit categories

Everything works EXCEPT edit colors(default) or add a newcategory. I get a error page not found.
Also.. I am new to php codeing, my header and footer edits worked if I use the "echo". If I use what I do in perl --- I get errors. Is this a PHP thing?
Great program... thank you.

I was able to add a new category, however I can't find where to choose a category. Also, everything seems to get added to the same category/calendar.

If all the files are installed in a sub folder of the root, error message when adding new categories. But, if all the files are at the root--no error message. everything works.
Thanks...

i'm having the same problem.....any ideas?

I am new to the calendar program, so I don't claim to be an expert, but here is what I did to remove the symptoms of the path problem:

ltw_classes.php - approximately line 210:
//********* davehack remove / before categories

//echo "<form name="/categories" method="post" action="/calendar.php?display=admin&task=categories">n";

echo "<form name="categories" method="post" action="calendar.php?display=admin&task=categories">n";

and again at approximately line 350
//*********** davehack ***********
// echo " window.location="/calendar.php?display=admin&task=categories"";

echo " window.location="calendar.php?display=admin&task=categories"";

Ok, as long as we're at it, we might as well let the main script be other than calendar.php.

I added:
// ********** davehack **********
$to_script = basename ($PHP_SELF);
at the top of the config file, but maybe should be at the top of the main calendar.php script. Then I changed all references to calendar.php in the classes script to $to_script (there were quite a few). Now the main script can be called whatever you like.
