I have a scenario like Rule "shopping cart total exceeds 4000, give 50% discount" when <condition> then <action> call Rule"if order is between 6 to 9 pm, give additional discount of 20 %" end Rule "if order between 6 to 9 pm give additional discount of 20 %" when <condition> then <action> end .............. Also i have a query like, Can we make rule like this Rule "shopping cart total exceeds 4000 give 50% discount" when <condition> then <action> Rule "if order between 6 to 9 pm give additional discount of 20 %" when <condition> then <action> end end Can we make rules like above?
