Welcome to our Community Forums! Thank you for your post and I'm very sorry to hear that you're having some issues registering for an online account! I understand how frustrating this must be! I'm here to help. 🙂
What error are you seeing? Are you able to upload a screenshot so we can look into this?
Are you able to try a different password? Certain things are too guessable are not allowed. No special characters, only letters and numbers. The password must begin with a letter and the password length must be between 8-10 characters.
Please let us know how you get on and if you need any further assistance with this.
