Do I pick error for each runner advancing?

[frachel]

How do I score this with the app:

Runners on 1st and 2nd, grounder to the 3rd baseman who makes an error.

I do:
In Play
Error
Click on 3b for "who made the error"
---
What happened to the runner on 2nd - I pick Safe and Third. The question I have is do I pick "advanced by batter" or "error"?
Same for man at 1st
---

Pick Held Up for batter.

You can use either Advanced by Batter or Error... whichever you prefer. The statistics will correctly only credit one error to the fielder.
