Why Does the System Say My Email or Name Is Invalid? (And How to Fix It)

Overview

Sometimes while booking tickets, you may see an error saying your name, email, or a field is invalid, even though your details look correct.

This article explains:

• Why these messages appear

• What they mean

• How you can fix them quickly

Common messages you may see

You might see messages such as:

• “This field contains characters that are not allowed”
  → This usually means special characters were used (for example: symbols, emojis, unusual punctuation, or extra spaces).

• “Please enter a valid email address”
  → This usually means the email is not in the correct format. A valid email should look like:
  john@gmail.com

• “Please select the field”
  → This usually means a mandatory question or required field in the checkout form has not been completed (for example: a dropdown, checkbox, or custom question added by the presenter).

• “Please agree to terms and conditions”
  → This usually means the Terms & Conditions checkbox has not been selected.
  Scroll through the page and make sure the checkbox is ticked before continuing.

How to fix email-related issues

If your email is being rejected:

• Make sure it follows this format:
  example@domain.com

• Remove any spaces before or after the email

• Do not add commas, brackets, or extra symbols

• Type the email manually instead of using copy/paste

• Avoid using browser autofill

Examples:
✔ john.smith@gmail.com
✘ john.smith@gmail,com
✘ john smith@gmail.com

How to fix name-related issues

If your name is being rejected:

• Use letters only (A–Z) where possible

• Avoid special characters such as:
  ! @ # $ % ^ & * ( ) _ + = { } [ ] | \ / < >

• Avoid emojis

• Avoid extra spaces at the beginning or end

• Try removing punctuation such as quotes or unusual symbols

If your name includes accents or special characters, try a simplified version:

• Instead of O’Connor, try OConnor

• Instead of José, try Jose

Check for required fields in the form

Sometimes the error is not caused by your name or email.

Scroll through the entire form and check for:

• Dropdowns that need to be selected

• Checkboxes that must be ticked

• Custom questions added by the presenter

If even one required field is missed, the system may block you from proceeding.

Avoid using browser autofill

Autofill can insert hidden characters that cause errors.

If problems continue:

• Clear the field completely

• Type your details manually

• Do not select saved autofill suggestions

Try a different browser or device

If the issue still continues:

• Try using Chrome, Safari, or Edge

• Try opening the page in an incognito/private window

• Try switching devices (mobile ↔ laptop)

This often resolves form and validation issues.
