PHP:

 

What error?

 

All fields marked with '*' are required to be filled up.

 

its hard to tell with out a live copy,

also use

foreach(array('var1','var2','var3') as $var){
$$var = htmlentites($_POST[$var]);
}

much easyer to read, and quicker to code, and you wont have people doing XSS

 

since php is serversided for 100%, there can't be anything wrong with your php code if it works in firefox. The only reason i can think of why the page doesn't work in IE is because of an HTML error. IF it's not too much trouble, would you mind posting your html code please?
