Emails not being sent

Hi All,

I am new to Eloqua. I have manged to fiddle my way around to create a simple email campaign. I have followed all the steps till the end and when i activate the campaign to send the emails, the report page opens up with all the factors at 0 and the no of emails sent is also 0. No emails are being sent out however the long the campaign stays active.

If anyone could please shed some light on how the emails are sent using the simple email campaign tool.

I am enclosing a screenshot of the page which shows up after i activate my campaign for you to understand better.

Thanks in Advance
