Thank you

Answer 1

i found the solution to my problem
first
$client = new nusoap_client("http://www.beetledev.com/webservices/bmiservice.asmx");
change to
$client = new nusoap_client('http://www.beetledev.com/webservices/bmiservice.asmx?WSDL',TRUE);
second
$result = $client->call('getBmiValue',array('w' => 62, 'h' =>167),null, 'http://www.beetledev.com/getBmiValue');
change to
$result = $client->call('getBmiValue',array('w' => 62,'h' => 167));
third
the thing is because there are two variable? (not sure with term), so it was kept in an array
please dont mind the variable name
$fConversionRate = (float) $result['getBmiValueResult'];
and done and i get my bmi result.
