Afternoon All. I am trying to create a portlet to be used by sales reps to work out a margin using a selling price and a cost price but i am having trouble trying to get it work. I have tried to create just a portlet and then tried to create a suitelet and a portlet using an iframe but i cannot get this to work either. I have never done anything like this before and there is not much documentation on it. Can anyone help me?
