Visual Form Builder Validation Not Working in IE9

Hi All,

I have implement two forms with Visual Form Builder, first form is validating fields on Submit and working great in all browsers including IE9, but the second form which is “Contact Us” form is not doing Validation in IE9, Validation works fine in all other browsers.

What could be the problem, can anyone help me in sorting this issue.
