I did a copy and paste of the text given and ended up with this:
Agency: Del Perro Police Department.
Region (Del Perro)
<Region>
<Name>DelPerroPoliceDepartment</Name>
<Zones>
<Zone>DELBE</Zone>
<Zone>DELPE</Zone>
</Zones>
</Region>
Backup XML listing.
<DelPerro>
<Agency>dppd</Agency>
<Agency>dpcr</Agency>
</DelPerro>
I don't know what I've done wrong, but for some reason the custom department isn't showing up correctly in the (backup menu), and vehicles aren't spawning. Any assistance would be greatly appreciated. ^-^
