totaled

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

'amounted' is the definition.
Both the answer and definition are past participle verbs.
Perhaps they are linked in a way I don't understand?

'baby deal being ruined' is the wordplay.
'baby' becomes 'tot' (I've seen this in another clue).
'being ruined' indicates anagramming the letters.
'deal' with letters rearranged gives 'aled'.
'tot'+'aled'='TOTALED'

'to' acts as a link.

Can you help me to learn more?
