I have read the manual for PDO, so that i can use it. Before i has my Script with mysqli, but i have read from Prepared Statemants and that they more comfortable and secure and so i has write. All was good, only that not want write in database. Okay thanks all, and im sorry that i disturb with the easy questions. All mistakes in the script i has found with google and the manual, but when not give message, there is problem. Often i not know the correct word which should use to search. For example i have a HTML Table, in this are much Code for calculate the Stock Portfolio. <Value, Dividend, Win, Lose> Thats okay, but i search a function with can tell php that should calculate all data in table. At moment i have write much Variables for every stock which is in Portfolio. Better were that i can copy the mathematical formula from one row/cell in next row/cell, like in excel. That i not found, because i not know what is the right words for searching. I dont know understand what i mean? My English not the best. Thanks for time and help. Silvio
