Err, you need to define your actual option...
code:
<Options>
<Skin>
<Properties>
<BoolVal Name="RemSearchBar">
<DispLabel>Remove the Search Bar</DispLabel>
<DispHelp>Remove the search bar from the contact list</DispHelp>
<Default>false</Default>
</BoolVal>
</Properties>
<OptionInterface>
...
</OptionInterface>
</Skin>
</Options>
