    hi i am trying to create an error on my servlet where the players chosen from selection fields are matched to those in the database. if they match then get their value. calculate the value of all players and if the total is greater then a designated budget output an error, else send on to DB..


    i thought firstly you would do something like

    //get parameters (eg string gk and string d1)
    int budget = 10;
    int sum = -1;


    if(gk.equals(p.getName()) ) {

    int g = p.getValue();

    if d1.equals(p.getName()) {

    int 1d = p.getValue());
    sum = ( g + 1d);
    }}
    if (sum > budget){
    //output error msg

    am i right??

    you should name your variables something better
    though maybe gk is goalkeeper and d1 is first defender?
    You will need to add all the values so think of a way of doing the same addition multiple (11?) times just using different fields.
    Also, you know the names of the fields so maybe define them somewhere, might be useful.
