Calling PublicReportService with two parameters

The following works when there is only one parameter, as soon as I add another, only the second one is passed:

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:v2="http://xmlns.oracle.com/oxp/service/v2">

   <soapenv:Header/>

   <soapenv:Body>

      <v2:runReport>

         <v2:reportRequest>

            <v2:parameterNameValues>

               <v2:listOfParamNameValues>

                     <v2:name>pLowerB</v2:name>

                     <v2:values>

                         <v2:item>1</v2:item>

                     </v2:values>

                     <v2:name>pUpperB</v2:name>

                     <v2:values>

                         <v2:item>10</v2:item>

                     </v2:values>

               </v2:listOfParamNameValues>

            </v2:parameterNameValues>

            <v2:reportAbsolutePath>/Custom/Testreport.xdo</v2:reportAbsolutePath>

          </v2:reportRequest>

         <v2:userID>UN</v2:userID>

         <v2:password>password</v2:password>
