Uncaught Typeerror: b.toLowerCase is not a function

I’m using SPServices and cannot figure out why I keep getting this error thrown from the jQuery library that b.toLowercase is not a function. Here are complete details of the error:

Here is my code. I’m using a CEWP that links to an html file containing all of the code:

$  ().SPServices({             operation: "GetListItems",             async: false,             CAMLViewFields: "<ViewFields><FieldRef Name='ID' /><FieldRef Name='docLink' /></ViewFields>",             listName: "PM",             debug: true,             completefunc: function (xData, Status) {                             $  (xData.responseXML).SPFilterNode("z:row").each(function(){                                             if ($  (this).attr("docLink" === 2)){                                             setTimeout(function(){                                             location.relod(true);                                             },3000);                                             }                             });               }              });
