Hi, I am trying to generate a online shipping calculator and that I doing by connecting with the FedEx. For the same purpose I have down loaded some code from phpclasses.org. But I am facing some problem in integrating the same in my project. I have to provide the calculation for both domestic and International with the following options- For Us Domestic I have to provide- 1) FedEx Ground 2) FedEx 2 day express 3) FedEx Overnight Express. And for International – 1) International Priority Express 2) International Economy. To get the different tag fields I have down loaded APIDirectTaggedTransactionGuideJan2007.pdf from the FedEx website. Code: include('fedexdc.php'); if ($_POST['uSubmit']!=""){ // create new fedex object $fed = new FedExDC('342464483','0');// I have not yet get the meter number $sType = $_POST['sType']; $ship_data = array( 75=> 'LBS' ,16=> 'Ma' ,13=> '44 Main street' ,5=> '312 stuart st' ,1273=> '01' ,1274=> '01' ,18=> '6173335555' ,15=> 'Boston' ,23=> '1' ,9=> '02134' ,183=> '6175556985' ,8=> 'MA' ,117=> 'US' ,17=> '02116' ,50=> 'US' ,4=> 'Vermonster LLC' ,7=> 'Boston' ,1369=> '1' ,12=> 'Jay Powers' ,1333=> '1' ,1401=> '1.0' ,116 => 1 ,68 => 'USD' ,1368 => 1 ,1369 => 1 ,1370 => 5 ,3025 => $sType // This I have added ); // Ship example $ship_Ret = $fed->ship_express($ship_data); if ($error = $fed->getError()) { echo "ERROR :". $error; } else { // Save the label to disk $fed->label('mylabel.png'); } } /* tracking example $track_Ret = $fed->track( array( 29 => 790344664540, )); */ echo $fed->debug_str. "\n<BR>"; echo "Price ".$ship_Ret[1419]; ?> <table> <form method="post" action=""> <tr> <td>US Customers :</td> <td> </td> <td><input type="radio" name="sType" value="FDXG"> Fedex Ground</td> </tr> <tr> <td> </td> <td> </td> <td><input type="radio" name="sType" value=""> Fedex 2 Day Express</td> </tr> <tr> <td> </td> <td> </td> <td><input type="radio" name="sType" value="FDXE"> Fedex Overnight Express</td> </tr> <tr> <td>International Customers :</td> <td> </td> <td><input type="radio" name="sType" value=""> International Priority Express</td> </tr> <tr> <td> </td> <td> </td> <td><input type="radio" name="sType" value=""> International Economy</td> </tr> <tr> <td> <input type="submit" name="uSubmit" value="Calculate"> </td> </tr> FDXE/FDXG </form> </table> Here in the above code I have given radio button values FDXG and FDXE for FedEx ground and over night express. I am not able to understand what value I shall pass for the other radio buttons. From the PDF documentation I do not really understand what value I shall use for tag field 3025 for all the above options. Can some one please help me out in this? Thanking you Abhik
