Thank you for your quick response
I made the change and am now getting a parse error in line 42:
Parse error: syntax error, unexpected T_STRING, expecting ',' or ';' in /home/donna100/public_html/modules/escal/calendar.php on line 42
This is line 42:
echo "<link href="theme/categories/categories.css" rel="stylesheet" type="text/css">";
I tried adding the \ character that was missing in line 41, but got a different error. So then I tried mirroring line 41 more exactly, but that did not work either, so put the script back the way it was.
I'm sorry for being so clueless! I only know enough HTML to be dangerous (and put up easy-to-install scripts like this one).
Thank you again.
