Request for help on CSS

Dear Kay

I am using SNS CSS-4.1.0.

I am trying to read and set the properties of XY graph widget using one action button.

My script attached to an action button (mouse click) is al follows.
***********************************
importPackage(Packages.org.csstudio.opibuilder.scriptUtil);

var color = display.getWidget("alphaProfileGraph").getPropertyValue(" trace_0_trace_color");

**************************************************************

Error shown in console at runtime is as follows.
*************************************************************
Wrapped org.csstudio.opibuilder.model.NonExistPropertyException: alphaProfileGraph does not have property:  trace_0_trace_color (script#3)


Pls let e know where I am wrong.

Regards
