"Not while answering and passing on"

Translation: Nicht beim Antworten und Weiterleiten

[Soglio]

Why "beim," and not "wahrend"?

[marziotta]

Nice question, I tried the same! Why "Nicht während antworten und weiterleiten" was not correct? Apart that I forgot the articles?

With verbs you need to use always Bei (or beim, if you contract it with dem)?
