Proc to send email notification on new entry

Hi,

I have a stored proc that I want to modify...

This existing sto proc was supposed to send an email whenever there is a new entry to a report...

There is also an audit table to keep track of sent emails.

As it stands the proc does not run if the audit table is empty...

I dont know what I am doing wrong, need help figuring this out... (I cannot use SSIS or SSRS email capabilities)
