Hi,
I need to make an weighted mean between several fields. Fields will have different weights. How would you achieve this? Do you have any tip? Any approach I could take?
thanks!

Is it per record over fields or over a field over several records? If you have a grid you have an event onrecord which will fire on every record. This event can be used to do what you want if the fields are in one record and you need to do this over each record.
If you have a final weighted mean over several records you have an event on footer which will fire at the end. I assume that you know how to calculate the weighted mean 
Hope this helps.
