Lots off Notice: Undefined offset:

I've set the php error_reporting in the php.ini to "E_ALL | E_STRICT" and now I see lots auf undefined things what makes the drastik tools will not work anymore.

Lots of this messages I find in the website errorlog:
---
Notice: Undefined offset: 1 in /var/www/web10/web/stats/drastictools/drasticSrcMySQL.class.php on line 152, (144, 145, 146) referer: http://www.agenito.de/stats/drastictools/ExampleGrid5.php

How can I get rid off this messages?

Does nobody else have this messeges as well?

I did get that messages. After inserting several isset-statements I decided to do the old

error_reporting(E_ERROR | E_PARSE);

trick on the beginning of the script to get on with what i first wanted to do: just use the grid.
