The error is:

"Breaking on JScript runtime error - Object doesn't this property or method"

And also it says that these error is on line 1071 of jquery.js

"elem[ name ] = value;"

function submit_new_avatar(form) {


var options = {

beforeSubmit: validate_form,

I found the thing that made an error. It was becouse I had input with name=action, without input with such name all goes ok, don't know why but obly this name of input makes an error.
