geocod variable in GWNBR Macro

[SongJL]

Hi, recently i used GWNBR in SAS which developed by Alan Silva.

i have succeed generating bandwidth with Golden Search but i failed on running the GWNBR macro code

Something that i dont know here is geocod variable.

i have filled it with latitude or longitude data but it still failed.

here i attach a full error output after i run the GWNBR code with latitude or longitude data

My code:

%gwnbr(data=oneweek,y=park_c ,x=f1_popavg f2_commerc f5_hotel f6_attract f7_bus_den avgfee offparking, lat=Ycenter,long=Xcenter,h=166.18966,gwr=local,
method=FIXED,geocod=Xcen,out=gwnbrDC);

Error:

i guess it is because of the false input of the geocod variable. So, what data i should have to be entered in the geocod variable ?

Thanks in advance.
