[jQuery] animate wont work on Opera 9


hi!
Im new to JQuery and my issue is animate is not working in opera.
here is the code,
function ajaxpost()
{
    var errors =
MM_validateForm('txtName','','R','txtEmail','','RisEmail');
if(errors)
    {
        //alert( 'The following error(s) occurred:<br />'+errors);
        $('#contactform').animate({
                    opacity:0,
                    width:"0",
                    },'slow',null,function(){
        $('#results').animate({
                    opacity:100,
                    width:"205px",
                    },'slow');
            });
    }
else
    {
        //alert('ss');
    };
function MM_validateForm() { //v4.0
if (document.getElementById){
var
i,p,q,nm,test,num,min,max,errors='',args=MM_validateForm.arguments;
for (i=0; i<(args.length-2); i+=3) { test=args[i+2];
val=document.getElementById(args[i]);
if (val) { nm=val.name; if ((val=val.value)!="") {
if (test.indexOf('isEmail')!=-1) { p=val.indexOf('@');
if (p<1 || p==(val.length-1)) errors+='- '+nm+' must contain
an e-mail address.\n';
} else if (test!='R') { num = parseFloat(val);
if (isNaN(val)) errors+='- '+nm+' must contain a number.\n';
if (test.indexOf('inRange') != -1) { p=test.indexOf(':');
min=test.substring(8,p); max=test.substring(p+1);
if (num<min || max<num) errors+='- '+nm+' must contain a
number between '+min+' and '+max+'.\n';
} } } else if (test.charAt(0) == 'R') errors += '- '+nm+' is
required.\n'; }
} if (errors) document.MM_returnValue = (errors == '');
    return(errors);
} }
};
