            EndLabel[0] = getParameter("Label1");
            EndLabel[1] = getParameter("Label2");
            EndLabel[2] = getParameter("Label3");
           EndLabel[3] = getParameter("Label4");

<PARAM NAME="EndLabel1" VALUE="110">
<PARAM NAME="EndLabel2" VALUE="150">
<PARAM NAME="EndLabel3" VALUE="100">
<PARAM NAME="EndLabel4" VALUE="170">

You have getParameter looking for the parameter that goes with "Label1", etc. rather than "EndLabel1", etc.

EndLabel[0] = String.valueOf(value[0]);
EndLabel[1] = String.valueOf(value[1]);
EndLabel[2] = String.valueOf(value[2]);
EndLabel[3] = String.valueOf(value[3]);
