This is an all in one autoresponder, email newsletter, shopping cart script. The problem is small. I've already more or less narrowed down which file the problem comes from but I am not knowledgeable anough with CGI email handling to fix it.
There are two problems and I think the code only needs to be slightly re-written.
1. Followup email for the autoresponder is sent every time the cron job runs. It should only send the followup email once and 'mark' as sent.
2. Post dated broadcast email is sent immediately. The date and time do not stick.
I will pay escrow immediately if you can start job the day project is closed. Please do not bid if you have no intention of following up. I've already wasted my time once. If you need to evaluate script first, please request via PMB.
