Location Hex

I am desig a module and I need especial condition in the units in some hexes.
Normally use this format:
{((GetProperty(“Individual Entrenchments Level”)==0) && (LocationName==N5603))}

It is a multy map game and I name N one of them. adn 5603 is the hex I need.
It is something wrong in this instruction???

Thansk in advance.
