It took me a while to understand that the interrogation mark it's actually the submit button. It really looks like an help button. Also, it's missing the cursor pointer.
First time I tried I input parent first, child second, seems more natural to a coder. I was confused with the result.
The arrow to change the parent/child relation is very confusing, giving no indication what is parent what is child.
I would suggest having a code like approach. Where child is inside (bellow/after) parent.
Also, clicking the arrows would in fact change the inputs values.
No need to keep arrows active, since we can swap as many times as we want.
I'm not a designer, but something like this.
