Can't feed name variables into get data table row

I was able to do this at one point but now it doesn’t work at all?

UPDATE: Further testing has revealed that my data table row names seem to be defaulting to numbers for some unknown reason.

This is how I set it up
It works if I simply choose the row name from the list but do not see why passing a variable through it would not work.

Turns out I was converting to string (byte) which is of course a number. I really should pay more attention.
