Connect Participant Scores(Column D) to their id Numbers(Column A) by sorting Columns B and C

I have 4 columns of data. I am trying to connect the Scores to the idNumbers.

Two sets of data. Column A and B are idNumber and Member names.

And Column C and D are Participants and their Scores.

The Participants are Members, but not all of the Members participated.

So, need a way to connect the Scores to the idNumbers by matching or sorting the Members and Participants.

I attached a small sample. The columns are actually 100's of members and participants long.

Ultimately,to create a weekly log of active Member's Scores.

Thanks in advance. I really appreciate it.
