i have two lenses on squidoo 1) http://www.squidoo.com/amazonhunter-review/ and 2) http://www.squidoo.com/review-micro-niche-finder/ The 1) i can add to any marketing group. The 2) doesnt even show up in the pull-down menu when i want to join a group, it's like this lens is not even there ! But i edited it a few times and published and added all it needs....i just can add my amazonhunter lens to groups, not the micro niche finder one ! thanks!!
Make sure you have enough modules for it to be considered 'published', or it will not be an option to add it to a group. It looks like your 2nd one only has 2 valid modules (guestbook no longer counts), I think you need 4-5 now.
Did you build them today? If you built them today you will not be able to add them to groups. You have to wait until they are considered "published" or live. That doesn't happen until the next day.
What RockDiesel said. Freshly published will see it as WIP status (Work In Progress). You will have to wait until it gets into Featured status. Which should be by the next lensranking.
