Hi Friend,

We have modified your code:

<Script language = JavaScript>
function validate() {
var checkD= checkDropdown(document.f1.choose.selectedIndex);
var checkR = checkRadio(document.f1.radios.value);
if (checkD != "") {
alert(checkD);
return false;
}
if (checkR != "") {
alert(checkR);
return false;
}

return true;
}

function checkDropdown(choice) {
var error = "";
if (choice == 0) {
error = "You didn't choose an option from the drop-down list.\n";
}
return error;
}

function checkRadio(checkvalue) {
var error = "";

for (i=0, n=document.f1.radios.length; i<n; i++) {
if (document.f1.radios[i].checked) {
var checkvalue = document.f1.radios[i].value;
break;
}
}

if (!(checkvalue)) {
error = "Please check a radio button.\n";
}
return error;
}
</SCRIPT>
</HEAD>

<form name="f1" onsubmit ="return validate();">
<SELECT NAME = choose >
<OPTION VALUE = "select">select</OPTION>
<OPTION VALUE = "NE" >North East</OPTION>
<OPTION VALUE = "NW">North West</OPTION>
<OPTION VALUE = "SE">South East</OPTION>
<OPTION VALUE = "SW">South West</OPTION>
<OPTION VALUE = "Midlands">Midlands</OPTION>
</SELECT>

<input type="radio" name="radios" value="male">Male <input type="radio" name="radios" value="Female">Female<br /><br />
<input name="Submit" value="Send" type="submit" >

</form>

Thanks
