Edd, The likely issue is that the layer name in the IdentifyConfig.xml has to match exactly with the name of the layer in the REST services directory.<layer>
<name>ParksPreserves</name>
<fields>SiteName,Address,ZipCode,PhoneNumber,OperationHours,Weblink</fields>
<linkfield>WebLink</linkfield>
<linkprefix></linkprefix>
<linksuffix></linksuffix>
<iconfield></iconfield>
<iconprefix></iconprefix>
<iconsuffix></iconsuffix>
<zoomscale>12000</zoomscale>
<forcescale>true</forcescale>
</layer>
Should be:<layer>
<name>Parks & Preserves</name>
<fields>SiteName,Address,ZipCode,PhoneNumber,OperationHours,Weblink</fields>
<linkfield>WebLink</linkfield>
<linkprefix></linkprefix>
<linksuffix></linksuffix>
<iconfield></iconfield>
<iconprefix></iconprefix>
<iconsuffix></iconsuffix>
<zoomscale>12000</zoomscale>
<forcescale>true</forcescale>
</layer>
and if that doesn't work than you have to escape the apostrophe with '
