Combining numbers by Reporting Names in BI Publisher

Content

We have a new element name for one that was set up incorrectly. The reporting name for both are the same. But they are showing up separately on the payslip. We are customizing the payslip for them to show as one. I was able to limit the name and current amount shown. For the YTD, we are looking to show both the YTDs combined (old and new element YTDs).

I tried the below code but it is totaling all the YTDs for all employees in the run instead of for the specific employee. Any idea how to address this?
