submit button not firing in Firefox

I have a simple script that works in I.E., but won’t fire in Firefox.

<script language=”JavaScript”>
function ValwrlContact(){
var filter = /^{^([a-zA-Z0-9_.–])+@(([a-zA-Z0-9–])+.)+([a-zA-Z0-9]{2,4})+$/;}

X=wrl_tellusform;
if (X.lname.value.replace(/^{^s*|s*$/g,””)==””)}
{
alert(“Enter last name “);
X.lname.focus();
return false;
}

else if (X.fname.value.replace(/^s*|s*$/g,””)==””)
{
alert(“Enter first name “);
X.fname.focus();
return false;
}
else if (X.repid.value.replace(/^s*|s*$/g,””)==””)
{
alert(“Enter the repid “);
X.repid.focus();
return false;
}
else if ( (X.phone1.value.replace(/^s*|s*$/g,””)==””) || (X.phone2.value.replace(/^s*|s*$/g,””)==””)|| (X.phone3.value.replace(/^s*|s*$/g,””)==””) )
{

alert(“Enter Phone number “);
X.phone1.focus();
return false;
}

else if (isNaN(X.phone1.value)||isNaN(X.phone2.value)||isNaN(X.phone3.value)||isNaN(X.phone4.value))
{
alert(“Enter VALID Phone number “);
X.phone1.focus();
return false;

}
else if (X.wrlemail.value.replace(/^{^s*|s*$/g,””)==””} || (!(filter.test(X.wrlemail.value.replace(/^{^s*|s*$/g,””)))} ))
{

alert(“Enter Valid email”);
X.wrlemail.focus();
return false;
}
else if (X.comments.value==””)
{
alert(“Enter a comment “);
X.comments.focus();
return false;
}

else {
document.wrl_tellusform.submit();
return true;
}

}

</script>
