The current syntax is described in

http://geuz.org/gmsh/doc/texinfo/gmsh.html#Specifying-mesh-element-sizes

Instead of

%<---test.geo (received)----------
Attractor Point{10} ={xx,xx,i};
Attractor Point{11} ={xx,xx,i};
Attractor Point{12} ={xx,xx,i};
Attractor Point{13} ={xx,xx,i};
...

Attractor Point{19} ={xx,xx,i};
--->%

try

%<---test1.geo (modified)----------
Field[1] = Attractor;
Field[1].NodesList = {10, 11, 12, 13, 14, 15, 16, 17, 18, 19};
Background Field = 1;
--->%

as attached.
