Identify multiple service using infoSymbol

MayJeff — Mon, 30 Jul 2012 01:58:17 GMT

I try to identify all layers on 2 different dynamic service to show on Infosymbol but only able to see the empty infosymbol without any attributes and infosymbol shows different time (on top of each other). Thank you.
Here is my codes:
