How do I find this problem? This works fine on app machine but does not work on production machine I obviously did not send something over, the question is what is it?

500 Internal Server Error
Script Error
Errorscript /finished_review.a5w line38
x_finishedcartonsre=a5w_run_Component(tmpl_finishcartonsre)
Error 1112
<>.Total subelement not found"


I just resent everything up to the production server and still have same error.
Thanks
Nick
