Hi Bryan,
Can you set up a demo of the issue on www.betasprings.com so we can review this? (Pls. use host / dnnhost to log in.) Just let us know your page when it's ready, ok?
Other questions:
1. Do other error messages show correctly?
2. When you go to Module config, Validation Configuration, would you happen to have the 'hide validation summary' checked?
Thanks,
Candace
