Troubleshooting with facebook pixel on weebly

General information for the website: I sell tutorials online Description of requirements/features: Hello, I am having problems installing my standard events FB pixels on my weebly website. Please read what I need before making an offer. Also, I am happy with my website! Please do not send me offers to create a new website for me (I know yours will be awesome, but I don't really need a new website). This is what I need exactly: -I have a FB pixel already. I have installed it on my weebly website. -My standard events pixel aren't recognized in my FB ad manager. I receive an error message (see picture attached) Thus, what I need is: -Get this error fixed so I can run my ads AND track conversions -Teach me how you did it Thanks! Please, don't offer me more services than what I am asking for. I believe it is a very simple task that can probably be done in 30 minutes by someone more familiar with FB than me. Thanks!
