Hey folks!
Just wanted to check in @jg80 and @JasperCreationss to see if you were still getting this error related to the query thinking that xLYNX is not a foreign key 
Relations between tables can be tricky, we might need to have you join us in office hours to see if we can work through this as there are lots of questions and moving parts to specify, test out and options to try to get this resolved.
