DOM/DHTML to pass vars 2x one function builds another call  using JAVASCRIPT

Hello  I have a startEditing function that has to "build" a href call to another function and pass 2 vars (a,b)
Those a,b are fine this startEditing function ( I can print them out to see them there), but I get an "a is undefined" when I click the new built href calling saverecord function I just built. what am I doing wrong?
BTW this all works perfectly except for when I add this passing of these vars - I need them for the save.

function startEditing(trObj,a,b) {
      var arrColumnNames = getColumnNames(trObj.parentNode.parentNode);
      var tdObjs = trObj.getElementsByTagName('TD');
      tdObjs[0].innerHTML = '<a class="save" href="#" onclick="saveRecord(this,a,b);" title="Save this record"><span>Save</span></a>';
      tdObjs[1].innerHTML = '<a class="cancel" href="#" onclick="cancelEditRecord(this);" title="Cancel editing"><span>Cancel</span></a>';
      for (var i=2;i<tdObjs.length;i++)
            if(i==3)
            tdObjs[i].innerHTML = '<input type="text" name="'+arrColumnNames[i-2]+'" id="input-'+arrColumnNames[i-2]+'" value="'+tdObjs[i].innerHTML+'" default="'+tdObjs[i].innerHTML+'">';
           else
            tdObjs[i].innerHTML = '<input type="hidden" name="'+arrColumnNames[i-2]+'"     id="input-'+arrColumnNames[i-2]+'" value="'+tdObjs[i].innerHTML+'" default="'+tdObjs[i].innerHTML+'">';
      return false;
}

function saveRecord(obj,a,b) {

      //           A      TD         TR    
      var trObj = obj.parentNode.parentNode;
      //              TR     TBODY      TABLE
      var tableObj = trObj.parentNode.parentNode;
      var inputObjs = trObj.getElementsByTagName('INPUT');
      var rowId = trObj.id;
      var url = tableObj.id;
      // Call SET/ADD method to save record to the database
      if ((rowId) && (rowId != ""))
            url += '.cfc?method=set&rowId=' + rowId;
      else
            url += '.cfc?method=add';
      for (var i=0;i<inputObjs.length;i++)
            url += '&' + inputObjs[i].name + '=' + inputObjs[i].value;
        // set the owner and level vars passed in
        url += '&ownerid=' + b;
        url += '&levelid=' + a;
      var response = wddxGetElement(httpRequest(url),'string');
      if (response.substr(0,2) != "id") alert(response);
      else {
            trObj.id = response.substr(3);
            stopEditing(trObj,false);
      }
