Congratulations—you've soldered the resistor to the board!

If one of the solder joints doesn't make contact with an end cap, reheat the cap and add more solder. If the solder isn't flowing neatly, apply flux to the joint before adding more solder.

Check if any solder has unintentionally bridged with a different pad. If so, carefully use your iron to heat the solder between the pads and separate the bridge. If the bridge doesn't want to separate, desolder it and try again.
