[jQuery] select list and tabs

[Mike Volmar]

I've got a form with jquery and regular javascript mixed (is this bad?),
along with 2 groups of jquery tabs with form fields within them.

I am trying to get a select list to activate a particular tab.

Here is what I have so far.

            $('#hispeed_type').change(function(event) {
                if(this.value == 2){
                    $('#containerA').triggerTab(4); // triggers third tab
                }
            });

#hispeed_type is the select list
#containerA tab 4 is what I'd like to activate if #hispeed_type value = 2

I get an error when I select the desired item on the select list
"$("#containerA").triggerTab
is not a function".

Isn't triggerTab a native jquery function?
