There is no custom script created for your account. Feel free to request some custom coding which can be done by MapBuilder.net staff.
As an example you can see the sample map created for
UrbanPlanet.org. That sample map contains city/locations
drop-down navigation which is not available for regular accounts. Also source code generating process was customized to match
some specific UrbanPlanet.org requirements.
If you need something special for your map talk 2 us.
