GA_googleAddAttr is not defined error

If you are using Google Ad Manager you can define custom attributes for targeting.

If you are getting a javascript error GA_googleAddAttr is not defined just make sure to put the call(s) to GA_googleAddAttr in a seperate <script> line, after the GS_googleEnableAllServices.

<script type="text/javascript">
GS_googleAddAdSenseService("ca-pub-0000000000"); 
GS_googleEnableAllServices();
</script>
<script type="text/javascript">
GA_googleAddAttr("ATTRB1", "whatever");
</script>
<script type="text/javascript">
GA_googleAddSlot("ca-pub-0000000000", "slotname_216x311");
</script>
