hi guys,
I'm new on Sugar and I'd like some help to understand how to customize the opportunity module:
I need to insert some new 'amount' fields:
Amount A
Amount B
Amount C
and I need to use the convertion rate as it works on the 'original' Amount field.
Can you help me to understand where is the correct function I need to use for that and how to do that ? (I'm really not a php developer ... :-( )

Thanks in advance
Daniele
