Validate email using jQuery
Briefly

The script is designed to validate email addresses upon button click, first checking for empty values and then validating the format using regex. An error appears to arise from checking the value of the button click event rather than the email input field. To fix the script, the validation of the email format should reference the correct variable containing the email address. Once corrected, the script should function as expected by moving to the next hidden div after a valid email is provided.
"If the input value is empty, we show an error message prompting the user to provide an email before further validation occurs."
"The regex is intended to validate the format of the email. However, it was incorrectly applied to the wrong variable, leading to validation failure despite the input being in the correct format."
