I would like for you to help me with this. How do I get in touch with you?
It is easy, you have to setup the export xml format according to your import structure or vice versa.
If both the JJB are having similar fields it easy to assign them imported fields to the existing JJB post fields.
If you want to include your feed in indeed then you must submit your feed to them they will examine n exclude/include.
Or If you want to import Indeed feeds into the JJB just make sure to assign the fields accordingly as I mentioned above.
If you cannot do this then I can do this for $50.
Regards.
