Error on FeatureLayer_Mouseover_Snapshot

MattJensen

I don't understand why I get the error "The prefix "esri" for element "esri:SimpleFillSymbol" is not bound." on line 68, when all I do is copy and past code from the original file to a new file?

Line          Code
68  <esri:SimpleFillSymbol id="mouseOverSymbol" alpha="0.5">
69   <esri:SimpleLineSymbol width="0" color="0xFF0000"/>
70  </esri:SimpleFillSymbol>
71  <esri:SimpleFillSymbol id="defaultsym" alpha="0.2">
72   <esri:SimpleLineSymbol width="1" color="0xEEEEEE"/>
73  </esri:SimpleFillSymbol>

The code looks to be bound to me

Thank you for your time,
