I am so embarrassed,

Can someone explain how anti-static wristbands are suppose to work?  I
always thought it was - they touch me, they touch the ground, I am therefore
touching a ground.

I can't find this on the net, and I figured it would be a no-brainer.  They
should conduct?  I have bought two different brands and neither one
conducts.  At least I can't get small current to run through them.

What am I doing wrong or how is my thinking wrong?  I simply put a 12V
potential difference across both ends and attached an amp meter and
nothing...  I would think these are defective, but two of them from
different companies?

Is it o.k. to attach them to the ground of my Power supply?  I use a PC
power supply that I took out of an old PC.  I am now questioning everything
that should be simple no-brainer.

Did I just get two defective wrist bands????  Grounds are no good if they
don't conduct! Right?????  AAArrrggghhh.  I know nothing.

Please help explain this very simple concept to me.

I will not mention my name - don't look at the "From" on the screen.
