Dear Andre, thanks for the reply. I think it is better to let the user decide if they want to add anything or not. In my case it lists over Euro 1 million each year under the column "loan". There is no loan. If you go down that road you also need to look a depreciation etc. Not your cup of tea. Let the user decide. If I put in "0" for the loan and "0" for the interest then it needs to show "0" in the field. And NOT another 0.06 Euro/Wp!!! There is a field where you can type in operational cost. Add the same field for interest or whatever. Very irritating. I find that amount as "annuities" and have no clue where it came from... "Ann. factor 5% cap./yr" hard coded, is it not?
