Send many data via input field to function in

Dear Users
when I add this to, default=0

Discu = models.DecimalField(max_digits=4, decimal_places=2, default=0)

then in

    Unites     = forms.DecimalField(required =False)
    Discu     = forms.DecimalField(required =False)
    class Meta:
        model= Invoice_billing

Many thank for all
Just another thing is that if I add the same item it doen’t return an error message in the form :slight_smile:
