What's the meaning for this error..

Wrapped net.sf.sahi.util.FileNotFoundRuntimeException: java.io.FileNotFoundException: c:sahi\userdata\scripts\td\values1.csv (The system cannot find the path specified)

i am trying to automate one name entry form using excel sheets , in that i am passing 3 values 1,lastname 2.firstname and address ..i have to insert atleast 100 datas per execution.please give me some sample script.

this is my script

_popup(/App.*/)._click(_span("Names[1]"));
_popup(/App.*/)._click(_span("Names Edit/Entry"));

function addNewuser($getlasname, $getfirstname, $getaddress){
try{

_popup(/App.*/)._setValue(_textbox("custNames\$LastName"), "$getlasname");
_popup(/App.*/)._setValue(_textbox("custNames\$FirstName"), "$getfirstname");
_popup(/App.*/)._setValue(_textbox("adrMainAddress\$txtFrom"), " ");
_popup(/App.*/)._click(_checkbox("adrMainAddress\$chkVerify"));
_popup(/App.*/)._setValue(_textbox("adrMainAddress\$txtFrom"), "$getaddress");
_popup(/App.*/)._click(_imageSubmitButton("Save"));
}catch(e){
_logException(e);
}
}

var $data = _readCSVFile("c:sahi/userdata/scripts/td/values1.csv")
for (var $i=0; $i<$data.length; $i++){
var $row = $data[$i];
addNewuser($row[0], $row[1], $row[2]);
}

the same script i found in our sahi testerdesk.com example only... but not working for me..


i used in this way also

function addNewuser($lasname, $firsname, $adress){

_popup(/App.*/)._click(_span("Names[1]"));
_popup(/App.*/)._click(_span("Names Edit/Entry"));
_popup(/App.*/)._setValue(_textbox("custNames\$LastName"), "$lasname");
_popup(/App.*/)._setValue(_textbox("custNames\$FirstName"), "$firsname");
_popup(/App.*/)._setValue(_textbox("adrMainAddress\$txtFrom"), " ");
_popup(/App.*/)._click(_checkbox("adrMainAddress\$chkVerify"));
_popup(/App.*/)._click(_checkbox("adrMainAddress\$chkVerify"));
_popup(/App.*/)._click(_checkbox("adrMainAddress\$chkVerify"));
_popup(/App.*/)._setValue(_textbox("adrMainAddress\$txtFrom"), "$adress");
_popup(/App.*/)._click(_imageSubmitButton("Save"));
}
var $data =_readCSVFile("c:sahi\userdata\scripts\td\values.csv")
for (var $i=0; $i<$data.length; $i++){
var $row = $data[$i];
addNewuser($row[0], $row[1], $row[2]);
}
