Greetings;

OpenSCAD https://www.openscad.org/version 2022.06.26.ai11958

I have several calls in this project that pass size arguments to a module.

For example:
line401:nut_mount_rocker(-.1,0,1);// two size trims, and optional nut
pocket controller
however:
line294:module nut_mount_rocker(l,w,sp)// V2
        {
        echo(296,l,w.sp);

returns:ECHO: 296, -0.1, undef yet later in this module: if (sp>0)// take out
nut pocket if sp>0 {
translate([0,0,14.95])cube([51.6,60.5,30],center=true);//nut pocket }
And it works. but the 0 in the call is called undef. but its being
undef'd is not an error? this module is called from within another
module like this: nut_mount_rocker(.8,2,0);// pocket for nut if non-zero
in third sargument, and it works! So the third argument is ok, why is
the zero not ok?

And that same echo then says:
ECHO: 296, 0.8, undef

So at least its consistent, but the parts don't fit right.
with 3 arguments, the first and third work, why not the 2nd one?

In this case, the 2nd is either 2 for correction, or zero for no correction, but it arrives at the module as undef in any
event, the parts it is making for the next 7 hours will be the wrong
size. I may as well abort the build. As PETG w 20% CF isn't cheap...
Thank you.

Take care & stay well everybody.

Cheers, Gene Heskett.

You have "w.sp" with a period rather than "w,sp" with a comma.

It seems like a bug that trying to specify a sub-element of something
that is not an array, range, or object does not yield an error.

Damn, I'm going blind. Thanks. Sorry for the noise everybody.
