Ribbon Workbench - Show Button on Related Entity value and Show Button by Sec Role

Hi, 
I have a button I want displayed on a Work Order.  This button should ONLY show WHEN:

-Related Account option set field = a certain value (bf_b2bsubtype = 979,580,001) 

AND 

-User SecurityRole = custom role (*BF Field Service - Dispatcher)

I need assistance figuring this out using a Display Rule.  Can anyone send a screenshot of what this would look like?  I am unsure because the solution I am working in is the Work Order, but it needs a value from the related Account.  I also have not shown/hidden buttons based on Security Role previously.  

Thanks!
