OTO Page Not Working - [Missing Purchase]

I keep getting this issue on my OTO upsell page. I’ve contacted Clickfunnels Support and they suggested to remove the header code from Funnelish for the paypal plugin… which didn’t work but I’m not doing that anyway because I need to use paypal.

I also can’t add my oto product on the general settings for some reason. It wont let me add any more. I have the oto product on the oto settings page but that doesn’t help. I havent yet tested this with paypal, but if anyone knows how i can fix this or even walk me through this i would really appreciate it.

Thanks,
Zuhal
