90% done. Having trouble with add_post_meta()

All bugs are squashed that I can find. However, I'm having inconsistencies and trouble getting the add_post_meta() to add a second matching value to the right post? Also, these were set to "true", doing so will make them unique, so set them to false or just let it default which is false. I will continue to try and get this working.. any input is much appreciated :)
