Tudosie, thank you for your answer. Aparently THFormula is more than I need. But many options on site doesn't work: Documentation, Demo, Order ---> Server not found Download ---> not working for trial version Besides, I am using Delphi 7. Does it work with Delphi 7? If it does, how can I get a trial version?
