hi

for your needs better call getFormData() before request and check if at least one value entered

I gave like:
var fn = myForm.getItemValue(“FirstName”);
var ln = myForm.getItemValue(“LastName”);
var c = myForm.getItemValue(“City”);
var st = myForm.getItemValue(“State”);
var cnt = myForm.getItemValue(“Country”);
var zc = myForm.getItemValue(“Zipcode”);
var em = myForm.getItemValue(“Email”);
var ph = myForm.getItemValue(“Phone”);
if (fn == “” && ln == “” && c == “” && st == “” && zc == “” && em == “” && ph == “” ) {
alert(“please enter atleast one value”);
}
my alert is working fine.but i want to display validation message in the form that"please enter atleast one field" at the top of the form.can u tel me how to this
