DMEObject is undefined???

I've cloned payratehistorymanager.htm.htm to display so a manager can see display alternate pay rates of his Direct Reports in EMSS.

When I try to add a DME query, that begins:

    var dmeObj = new DMEObject(authUser.prodline,"prrates");

...I get an error that says DMEObject is undefined.

Why would DMEObject be undefined?

TIA...ChuckM
