Great thanks, I have it working, just cant get it to highlight.
I changed that line of code to this:
fl.setSelectionSymbol(new esri.symbol.SimpleLineSymbol(esri.symbol.SimpleLineSymbol.STYLE_DASH, new dojo.Color("blue"));
And I also changed:
From
"esri/symbols/SimpleFillSymbol",
to
"esri/symbols/SimpleLineSymbol",
Any ideas, your help is really appreciated btw
