The facebook event setup tool doesnt open (Fix the Button) so that event Setup Tool opens. -- 2

I want to track via Facebook Conversion, but the Facebook Event Setup Tool does not open. I am looking for a programmer who can debug Das via his Facebook account, using the Facebook Event Setup Tool and (via the pixel and the "Re-track" button) the two yellow buttons. On the other landing pages I have, the Facebook Event Setup Tool opens, but not on this LP. I think it is the button that is not recognized as a button. My client doesn't want to expose their account or add someone, so please debug it through your account. it's this landing page
