Declared variable reads as null

I have two variables user and group declared. When I run the function removeGroupFromSite(), it should alert me saying please select a group but the variable returns as null. I assume it's because it's getting the value of the select and not the selected option? How would I get the value of the selected option within these variables?

var user, group, strHTMLSiteUsers, strHTMLSiteGroups, strHTMLAvailable, strHTMLAssigned, arrOptionsAssigned, arrGroups, arrUsers, intOpts, booMatch, booErr;

$(document).ready(function(){ 
    user = $('#my_SiteUsers');
    group = $('#my_SiteGroups');
    groupsAssigned = $("#my_SPGroupsAssigned");
    groupAvailable = $("#my_SPGroupsAvailable");
    userAssigned = $("#my_SPUsersAssigned").html("");
    userAvailable = $("#my_SPUsersAvailable").html("");

    $("button").click(function() { return false; });

    populateUsers();
    populateGroups();
});

function removeGroupFromSite(){
  //check if default group selected 
  alert('cp'+group.val());
  if(group.val() !== "default"){
    var removeConfirm = confirm("Are you sure you want to delete group: " + group.val());
    if(removeConfirm){
      $().SPServices({
        operation:"RemoveGroup",
        groupName: group,
        async:true,
        completefunc: function (xData,Status){
            alert(group + " succesfully deleted");
        }
      });
    }
  }else{
    alert("Please select a group");
  }
}

HTML

<select id="my_SiteGroups" style="width:200px;" onchange="RefreshUserLists()">
        <option value='default' disabled="disabled">Select a group</option>
      </select>

simple fix

remove disabled="disabled" from <option>

disabled property does not carry the value from DOM as it was disabled.

Reference

disabled

This Boolean attribute indicates that the form control is not available for interaction. In particular, the click event will not be dispatched on disabled controls. Also, a disabled control's value isn't submitted with the form. This attribute is ignored if the value of the type attribute is hidden.
