# Undefined value error

 * Hello, in both fields where a number should be selected via a dropdown menu, 
   selecting the value ‘0’ is not possible. When I select the value ‘0’ and press
   the ‘Send’ button, I receive a warning message stating ‘Undefined value was submitted
   through this field.’ There was no issue before the update released a few days
   ago, but after installing the update for Contact Form 7 on March 2, 2024, this
   problem started occurring. I would appreciate your assistance.

 * Hi, thank you for your patience. I can’t reproduce the issue, but I see there’s
   a lot of threads about this error.
 * Are you dynamically adding values to your dropdown? If so, you’ll need to remove
   the newly added validation check and add your own. This plugin only finds and
   selects existing options, it doesn’t create new ones so I don’t think this plugin
   will cause the error on its own.
 * Here are some threads I found that might help you:
