jquery, perl, form and serialize command not working IE browser

I have t开发者_开发问答his form section with dynamic clone of select drop down menus.

The form are passing the values into the serialize.

 var data3 = $("#advance_mode_inputs").serialize();

Firefox works but in IE, it isn't working. Any ideas? There were no errors reported by the IE browser.

regards, Gordon

Nevermind,

I discovered that I was missing the </form> for this form.

Another question, any good tools to do checks like this?
