Suffering with Cron job error

Tried the script given during installation,,, gave two errors,,

MAILTO=myemail@gmail.com
* * * * * cd /home/username/public_html/periodic; /usr/local/bin/php -q cron.php

Then tried these other method,,

MAILTO=myemail * * * * * /usr/local/bin/php -q /home/sitedir/public_html/periodic/cron.php
and 
MAILTO=myemail * * * * * /usr/bin/php -q /home/sitedir/public_html/periodic/cron.php

then now getting just this error /bin/sh: access-logs: command not found

even put the path to my blank php.ini, like below but still didnt solve the issue 

MAILTO=myemail * * * * * /usr/bin/php -c /home/sitedir/public_html/php.ini -q /home/sitedir/public_html/periodic/cron.php

Any thoughts on why isnt it still working... ?

Any one ????????

you are trying to add this to php.ini?

Question are you putting

MAILTO=myemail * * * * * /usr/local/bin/php -q /home/sitedir/public_html/periodic/cron.php

into cron command line ?

I am putting the script in cpanel>>cron jobs>> in the "command" box. thats where it the script should go right? 

This portion goes into command line /usr/bin/php -q /home/sitedir/public_html/periodic/cron.php

The * * * * * * go separately into minute, hour, day of month, month, day of week,

And your email goes into the Scheduler notification so you get the results or errors sent to you

Saying that i am not using cpanel

Ok good, the error is gone now..

BTW the site functions properly with out  setting up this particular crone job,, then whats the purpose of setting up this cron job?

to process videos, send mass mails and other tasks in sys_cron_jobs table.
