Trevor,
What you have found is a "feature" that PMI has introduced into their system: As soon as you accept ANYTHING from their dropdown boxes, then your submission will fail. That is why all my "how-to" videos mention this.
Check this video here:
traffic.libsyn.com/pmpodcast/PDU_Claim_4...PrepCast_on_CCRS.mp4
and fast forward to about 2 minutes.
Your only option is to cancel/delete your submission and then repeat it WITHOUT selecting anything from their dropdowns.
I apologize (n the name of PMI) for this particular "functionality".
