Label Dynamic Back Color on objects

Hi folks,

Has anyone used the advanced scripting tab in Label Forms for an opaque rectangle to have it's backcolor read from a field in the cursor? I am generating RGB() settings in the underlying cursor to set the back color of a rectangle.

I tried to create Property=BackColor and value =evaluate(labelbc) Where the field labelbc had RGB(255,0,148) etc.

Thanks
