Are these 50 lines static or copies og user entered data?

 Hi, I am working on a form including three fields: Weight, Price and value. ( All decimals)If price is entered then value is calculated and if value is entered then price is calculated.I implemented the calculations by rules (Not code behind and not as the default value formula as these are conditioned) I am using Danish settings ...

It is quite simple to do that in the code behind. You can for example have a "Clone" button and hitting that button takes the current record and clones it X times using the AppendChildElement method.
