Cron Job Error

[ravis]

I have a problem with VPS hosting plan(purchased from startlogic). I have purchased VPS hosting plan for Cron Tab but still I am unable to run this on my website.

this account is a plesk 8.6.


Please advice me how to run this CRON TAB without throwing any error. The error is as follows:

/bin/sh: 0: command not found.
