Need help getting a cronjob to work and fix a listing problem

I have a site that uses PHP / MYSQL, CURL and CRON. It uses a program called open realty and another addon called IDXMANAGER. The website is not getting it's photos and listings updated because the cronjob does not appear to be running right. Also the IDX has a slim window in which the ftp access will let the server in, they have to be timed to run at a precise time of day. There is only a 4 hour window for this to happen. I need all of this fixed before Sunday. It should be a few hours of your time, before the window and durring the window to see if all is working correctly. ## Deliverables I have no time to waste.
