I see that you’ve already removed the Interest Rate from your widget, but my colleague Maria has checked your widget before and replied in the chat and your support ticket.
As she said, to adjust the formula, please go to the Calculations section on the Build tab and click on the "Estimated Monthly Payment " formula:
I won’t change anything, I need the interest rate to be hidden from display along with total repayment and total interest hidden, could you amend this for me please as the above does not make sense
