Thanks, in fact, I would like to calculate the values of each line and give, for each one, the result in the Total row, the difference is that in each cell there is a number, but a character, essentially are three M, P, N, for each of the characters matches a value, if the input character is different from the three the value is null. Nellla line indicates the total must give me the sum total.
Excuse my little jquery experience, I know php and mysql enough. The code that you sent me I can not put it into practice …
I have little experience … you can give me an example more explicit? I would be very grateful ….. Carlo.
