How to compute field with conditions based on other fields?

Question

Hello Everyone,
Can someone explain me what's wrong with my code ?
i'm getting the following error:
UnboundLocalError: local variable 'total_amount' referenced before assignment My Code:
payment_id  = fields.Integer( string = 'Payment ID' )      ammount  = fields.Integer ( "Value 1" )      rate  = fields.Integer ( "Value 1" )      total  = fields.Float ( string  =  'Multiplicar' ,  compute  =  '_compute_total' )
@api.depends  ( 'ammount' ,  'rate' , 'payment_id' )      def   _compute_total  ( se

Hi,
You are getting this error because     you haven't assigned what value should     * total_amount *   *   *hold , You need to define the variable before using it .
def _compute_total (self):
for record in self:
if str(record.payment_id) == 1:
record.total_amount = record.ammount * record.rate
elif str(record.payment_id) == 2:
total_amount = record.ammount / record.rate
else:
*self.total = total_amoun*t   // Error is in this line , because you need to define total_amount before assigning .   *
