Audience practice - to get them going outside! (10)

I believe the answer is:

housetrain

I'm a little stuck... Click here to teach me more about this clue!

'get them going outside' is the definition.
I don't know anything about this answer so I can't judge whether this works.

'audience practice' is the wordplay.
'audience' becomes 'house' (term for a theatre's audience).
'practice' becomes 'train' (I've seen this in another clue).
'house'+'train'='HOUSETRAIN'

'to' is the link.

Can you help me to learn more?

I've seen this clue in The Irish Times.
