The index on _setCustomVar cannot be greater than 5, see: https://developers.google.com/analytics/devguides/collection/gajs/gaTrackingCustomVariables

            <script type="text/javascript">
          var _gaq = _gaq || [];
          _gaq.push(["_setAccount", "UA-11223344-1"]);

          _gaq.push(["_setCustomVar", 4, "ab_test_four", "c", 1]);
_gaq.push(["_setCustomVar", 5, "ab_test_five", "a", 1]);
_gaq.push(["_setCustomVar", 6, "ab_test_six", "b", 1]);
_gaq.push(["_setCustomVar", 7, "button_color_on_signup", "green", 1]);
_gaq.push(["_setCustomVar", 8, "button_color_on_login", "green", 1]);
          _gaq.push(["_trackPageview"]);
