I have the following code to bulk upload to several different tables

There are two problems that need to be addressed and i can't seem to work them out.

1. This script works, but at (line 126) "// Now add the job to the job table" entry I am getting two duplicate records created in the jobs table. All other tables are behaving normally.

2. I need to be able to check if the new user is there in the first place. If it is, to jump ahead and add the job record against that user (and employer) id, if not to go ahead and create the user.

I've been working on this for ages now and its these two things that are holding me up, but i'm stumped now, any help or pointers in the right direction would be really appreciated.

Many thanks
