Using an IF statement from mulitple data sources to single source

I have a workbook with several sheets. The first sheet has one individual id numbers vertically and multiple submissions going across horizontally.
The second sheet has each individual id number listed by how many submissions...so each person's id number may be listed more than once in a column depending on the number of submissions as opposed to the first page where the id is only listed one per row with multiple submissions in the row.

Each of the different submissions has been assigned a score to be totaled at the end by the single id number. Each person has also been awarded a one-time additional score based on the amount of time with the company. Submission scores range from 0, 1, and 2. If a person receives a score of 0 on one of the submission then the score awarded for their time with the company is not to be considered, only their submission scores. Scores above 0 will be considered along with the score for the submission.

The formulas I have tried is:

=IF('4. Scoring'!L4=0,O2=0,O2+P2)

=IF(AND(A:A='4. Scoring'!A:A,'4. Scoring'!L:L=0),O2=0,O2+P2)

But both are still considering the tenure score for persons that have 0's. I need to make sure that even if a person has more than one submission and a 0 for only 1 of those submissions the tenure score and the other submissions scores are still added together.
