[jQuery] Plugin function does not exist.

[riegersn]

        $.fn.selectMatch = function(x) {
                for (i=0; i<this[0].options.length; i++) {
                        if (this[0].options[i].innerHTML == x) alert('found 
it');
                }
                return this;
        };

in my script im calling

$('#optionselect').selectMatch('test');

firebug blows up and tells me that selectMatch does not exist.

I have other function in this plugin that work, but they extend only
jQuery itself ( $.funcname ) not $.fn.name

Any ideas?

Thanks
