Not hard at all, but I posted this at 10:35 last night. Stores were closed.

How hard would it have been to go buy some?

and also put soldering
paste on the 1/2 inch pipe.

But, evidently, didn't clean it first, since you didn't have any
sandpaper.

I inserted the pipe inside the coupling, and
heated the couplign up with a torch. I tried to put solder on the end of
the coupling and the pipe, but the solder didn't go around the coupling
to
form a seal. In fact the solder made a complete mess adn I ended up with
clumps of solder in one spot.

Is this by any chance the first time you've ever tried to sweat-solder
copper
pipe? If so... spend a few bucks on some spare fittings, and practice on a
few
joints first.

What the heck am I doing wrong?

Improper cleaning of the pipe and fitting didn't help you at all, but it
sounds like the biggest problem is most likely that you:
a) didn't get the fitting hot enough before applying the solder, AND
b) tried to solder directly in the flame.

Take the joint apart. Clean everything properly this time (with a wire
brush
or sandpaper). Flux both parts, making sure that you're using the right
type
of flux for your solder. Then try again. Heat only the fitting, and apply
the
solder to the pipe, directly opposite from the flame.
