It seemed to be fine when I tried it.
Tuan's error checking is pretty bad. I had trouble getting it to accept the email input until I told it "x@y.net" and then it accepted input and sent me to a page with "invalid site certificate". What Joomla version are you using and which payment plugin?
Try viewing you site with something other than IE, perhaps Firefox - it may look different depending on browser.
