foreach() and point() problem

[foam]

Hi!

 

I'm using an attribwrangle on some geometry and when I try to loop through the neighbours and get their value 'foo', it returns zero where as looking at P returns (I'm assuming) the first/last P in the neighbour array.

 

Anyone know what I can't read @foo?

 

Thanks.

@foo = 100;

foreach(int i; neighbours(0, @ptnum))
{
    v@test_P = point(0, "P", i);
    @test_foo = point(0, "foo", i);
}

Solved thanks to Jacob -

 

foo doesn't exist before the attribwrangle and point(0 ,"foo", i) is looking for the first input
