Required field returning curly brackets

I have created a series of multipage nomination forms, with most of the fields being marked under the validation tab as required. After multiple tests from various computers (admittedly, all in-house) we published because every field we needed was forcing some data to be entered, and the email contact fields required at least something formatted as an address be entered. Then we get our first live submission. The multi-line fields came in fine with data intact, but we received lines like this for all of the required fields:
Your City {Your_City}
Your State {Your_State}
Your Zip {Your_Zip}
Your Email {Your_Email}

I am a relative newcomer to Joomla! and all of the Modules, components and add-ins so any direction on what I have done wrong would be greatly appreciated. This is Chronoforms v4 on Joomla! 1.5.26

Hi JJacobs634,

The required field setting is just a client side (browser) validtaion, it may be skipped if the user has javascript disabled on their browser for any reason, if you want to enforce this rule then you should check the "server side validation" (FAQ available) and configure it to check the important fields!
