Hi all, I have prepared a simple spreadsheet to record debtor payments and determine the unpaid balance at any given time.However, I would like to add a Userform into which I can enter a payment amount, the date of payment and perhaps the interest rate. I say perhaps because the rate may change at a particular date and my spreadsheet is not sophisticated enough for that at this stage.I searched the knowledge base for assistance and found a listbox that I may be able to utilise. The problem is that I want to enter a new row each time I enter the new data and I want that row to contain the formulas necessary to do my calculation.Before I get into deep water can anyone suggest a simple way to achieve my desired outcome? Unfortunatley, I was unable to attach an example of my spreadsheet.Any help will be appreciated.Regards,Greg.
