Introduce the value of an arithmetic operation to a bundle by name

[Fernan1988]

I want to set the values of a bundle by name, by using an arithmetic operation that uses the value of another bundle by name. The thing is that when I do this, I get this error: You hve connected an input of subtract to an input of bundle by name. Change one to output, or add a source.

Can someone please tell me how to fix this?

Thanks in advance!

To get the x or y value, you need the UNBUNDLE by Name. The error message it's pretty clear that you don't have a source.
