quietthunderdesigns on "[Plugin: Formidable Forms] Center form in Revolution Slider"

Hello,

I'm trying to center a form in Revolution Slider...have tried centering via the slider and also with <center> tags but neither works. Example here: http://celebrityhideaways.com/homepage-2/

Any idea how to fix this? Please advise.

Thanks for your help!
