How to access the (field) value of a Control on an Applet in a Physical Renderer

Hello,

I have a Physical Renderer that I am working on, I am able to get the control, but I need to access the actual field data of the control. How do I do this?

...

    var ac_controls = this.GetPM().Get("GetControls");
    var stOAKStatus = ac_controls["OAKStatus"];
    var sOAKStatus = stOAKStatus.GetValue();
    var sOAKStatus2 = stOAKStatus.GetInputName();
    var sOAKStatus3 = this.GetUIWrapper(stOAKStatus).GetValue();
    var sOAKStatus4 = stOAKStatus.GetDisplayName();
    var sOAKStatus5 = this.GetPM().Get( "OAK Status" );
    if ( sOAKStatus == "Requested" )
     $("[name='" + stOAKStatus.GetInputName() + "']").css("color","orange");
    else
     $("[name='" + stOAKStatus.GetInputName() + "']").css("color","blue");   
            }
            SiebelJS.Extend(OAKEpicRFHStatus, SiebelAppFacade.PhysicalRenderer);
...

I've tried all the above and nothing seems to work,
