cron error

any idea how to fix this error?

Here is the suggested cron from the install

* * * * * cd /home/christia/public_html/periodic; /usr/local/bin/php -q cron.php

THANKS

You don't need the stars in the command. They are referencing the times and dates of the job, you've specified that above.

Edit: while every 30 minutes might work fine I would suggest setting it to tun every minute and only reduce that if a good reason presents itself. 

Thanks, I should have picked that up...  thanks for helping out.

Any time old chap!
