How do I do a Cron Job as that is all i am getting. This is what I put php /home1/littlfk0/public_html/dreamingofpspco/admin/includes/extra_datafiles/currencyupdate_openexchangerates.php and this is what the emai says. I run admin the following found below

Status: 404 Not Found
Content-type: text/html

No input file specified.

But would this work
/usr/bin/GET http://www.dreamingofpsp.co.uk/admin...hangerates.php

I want the cron job to run openexchangerates every half an hour.

Any help would be appreciated
