Hi Colette,
Sorry to hear you're having trouble! Please note this forum is for API Developers. For support questions, it'd be best that you reach out to our Customer Support team: www.eventbrite.com/support/contact-us. Be sure you are logged into your Eventbrite account when you visit the Contact Us page so you can access support.
I will say, it sounds like you may be sending your personal invitation link, which will pre-populate your email address at checkout. This is because email invitation links are unique and only intended for use by the recipient. Your event URL, which is shareable and specific to your event, can be found at the bottom of the Event Dashboard under “Your event URL”. For more tips on promoting your event, check out our Help Center article here!
Best,
Natalie
