All your top level folders (bin, config, mods, etc.) are in a subfolder inside the archive. They should all be a the top level.
Your modpack.jar is named "modpack.jar.jar". Make sure you turn on visible file extensions to prevent this problem.
Your pack settings, Forge version and mod versions are all messed up. You have your pack set to MC 1.7.5, your Forge version in the pack is 1.7.2-1060 (not even the latest recommended) and a mishmash of 1.7.2 and 1.6.4 mods. Pick a platform and make your modpack for that ONE platform/version.
