Hi. Installed latest version of GF today to get the conditional form submission functionality, however, it appears broken to me. I get a section under advanced form options that reads 'To enable conditional logic use' and that's it. There's no checkbox, or other form fields nearby. The next field is 'CSS class name'.
I'm using Chrome 5.0.375.99.
Just checked and it works fine in Firefox 3.6.7 so appears to be a chrome issue.
