Concatenate multiple values

[mcpizzle]

super helpful...I'm attempting to do a modification of this.

I'd like to concatenate ID numbers from all related rows within the table itself. See the attachment.

Counting and Summing for all related values is in the table (see column D), but a reporting of the values themselves? Unsure how to do this. Any great ideas? Thanks.
