I have a simple PHP signup file, but I got error. When use it on firefox 3.6, it shows errors correctly when forms filled blank. But on other browsers, it doesnt show any errors. I saw the source code on output page, it doesnt show errors text at all. I dont know why, please help me to fix it.

I also attach file here, whats wrong with it?
Thank you very much
