ITN 2015: How should I fill in table 1.1?

Table 1.1 asks you to fill in lead beneficiary and lead Number and Lead Participant Short name. In case you are confused what to fill in where, here is a clarification by REA:

"Under “Lead Beneficiary No.” you can write the number of the beneficiary from the list of participants and under “Lead Participant Short Name” the short-name of the beneficiary leading the work-package."
