代碼如下：

Truck_Number = Request.Form["Truck_Number"]; 
Truck_Make = Request.Form["Truck_Make"];   
Truck_Model = Request.Form["Truck_Model"]; 
Truck_Year = Request.Form["Truck_Year"]; 
Truck_Vin = Request.Form["Truck_Vin"]; 
Truck_Empty_Weight = Request.Form["Truck_Empty_Weight"]; 
Truck_Assigned_To = Request.Form["Truck_Assigned_To"]; 
Truck_Assigned_Date = Request.Form["Truck_Assigned_Date"]; 
Truck_Plate_Number = Request.Form["Truck_Plate_Number"]; 
Truck_IFTA_ID = Request.Form["Truck_IFTA_ID"];
