Ciao a tutti
devo creare un calcolatore per cui l'utente inserendo alcuni dati(fra cui percentuali) puo' avere il risultato di quanto andra' a ricevere per una vendita standard di una casa. Ho creato percio' un form dove ho inserito i campi e un foglio esterno dove c'e la funzione javascript che dovrebbe aime' permettergli di far cio'....Premetto che sono principiante in javascript percio' se qualcuno puo' darmi qualche dritta controllando il code che ho creato gli sarei molto grata...Grazie tanto in anticipo a coloro che mi risponderanno.

Questo e' lo script esterno:
// JavaScript Document
editabile=false;
function calculator() {
//Var
var smv = document.frmCalculator.strsmv.value;
var to = document.frmCalculator.strtypicaloffert.value;
var tot = ""
var fea = document.frmCalculator.strfEA.value;
var legalfee = document.frmCalculator.strelf.value;
var icms = document.frmCalculator.stricms.value;
var feat = ""
var totea = ""
send=true;
// script for your house is worth
if ((smv == "") || (smv == "undefined")) {
alert(" Please insert a Estate Agent's suggested market value for your house");
document.frmCalculator.strsmv.focus();
send=false;
return send;
}
// script for Typical offer from possible buyer
if ((to == 7)) {
tot = smv - (smv / 100 * 7)
}
else{
tot = smv - (smv / 100 * 8)
}
//script fee to Estate Agent
if ((to == 2)) {
tot = smv - (smv / 100 * 2)
}
else{
tot = smv - (smv / 100 * 2.5)
}
//script for real value
if ((totea == 0)) {
totea = smv - tot - feat - legalfee - icms;
document.frmCalculator.Write.strtotalEA(totea) ;
}
}//end function
Vi sarei grata se potreste aiutarmi il piu' presto possibile....GRAZIEEEEEEEE!!!!
