This image shows a typical FastLane error screen that may be encountered when submitting a preliminary proposal under the DEB Core Programs Solicitation. 

Figure 1. FastLane Submission Error Screen

Bulleted items appearing under the Proposal Errors header, in this case “No Proposal Classification”, must be corrected to allow submission of the preliminary proposal. Bulleted items appearing under the Proposal Required Items header are prefaced with the phrase “unless otherwise specified in a solicitation” and in most cases are excluded from the DEB Core Programs Solicitation. Submitters should check the solicitation to confirm the items should be excluded and then proceed with submission. FastLane will not prevent submission of a proposal for bulleted items under Proposal Required Items.
