CRM JS Client Script - Multiply 2 fields.

CRM JS Client Script - Multiply 2 fields.

Hi guys,

Can anyone help with the scenario below?

I need a JS Client Script so I can auto populate a subform field on the CRM Deals Module as a result of a multiplication. I can play around with deluge, but I have no idea how to write Java scripts.

Three subform fields involved: 

A. Individual Price (Currency)
B. Qty (Number)
C. Total Price (Currency)

I need A * B = C

I appreciate any help sent this way!

Best,

Rodrigo.
