Ethereum javascript paquete web contrato inteligente

Estoy tratando de enviar el valor del menú desplegable html al contrato inteligente, el valor se extrae de la función js pero no puedo agregarlo a la función SetVote, la ejecución se interrumpe allí.

Html:
 <div class="dropdown">
            <button class="btn btn-vote btn-secondary dropdown-toggle" type="button" id="dropdownMenuButton" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
              Dropdown button
            </button>
            <div class="dropdown-menu" aria-labelledby="dropdownMenuButton">
              <a class="dropdown-item" href="#">value1</a>
              <a class="dropdown-item" href="#">value2</a>
              <a class="dropdown-item" href="#">value3</a>
            </div>
          </div>


JavaScript:

 App = {   web3Provider: null,   contracts: {},


  init: function() {

    // Is there an injected web3 instance? if (typeof web3 !== 'undefined') {   App.web3Provider = web3.currentProvider; } else {   // If no injected web3 instance is detected, fall back to Ganache   App.web3Provider = new Web3.providers.HttpProvider('http://127.0.0.1:9545'); } web3 = new Web3(App.web3Provider);  

    return App.initContract();   },
