EXCEL TO GH QUERY

I am reaching out to you regarding a Grasshopper script query that I need some help with. So I am using a GH script for space planning that looks like this:

Now the issue that I am facing is that the excel file I have created has rooms under departments with the same code names. The script seems to only identify unique codes for each room. For instance, Inpatient surgery has 25  PACU Beds and all of them have the code 50001B.

When I select 50001b from the xl file and update the script, it seems to only highlight a single room in rhino instead of all the rooms tagged as 50001B. I am wondering if there’s way in Grasshopper to change the script from reading each code as a unique entity to having GH read all the rooms with the same code?

So that way, when I bake the script, it identifies all the rooms tagged as 50001B in rhino instead of just 1. 

I have attached the GH script and pdf of these images with this post. Please let me know what the best solution would be! 

Thanks!
