>From what I've seen so far, you're far from hopeless with electricity. Are
you sure that your multimeter is set to read resistance? You are correct,
with the probes not touching anything the reading should be infinity (or
close enough :)) and with the probes touching it should read a solid zero
(should be stable). In any case, if you get the same reading in air as
connected to the two leads of your cable, it appears that you have a break
somewhere in the cable.
