actionscript 3 - Flash Error #1009 on mouse click -

i have movie clip called androideye2, has 4 frames.

i have code on 'main menu' scene:

function eye1(e){ androideye2.gotoandstop(2); }  function standstill(e){ androideye2.gotoandstop(1); }  viewmerchandise_iconb.addeventlistener(mouseevent.click,viewmerchandise1); function viewmerchandise1(e) { gotoandplay(1,"viewmerchandise1"); }  viewmerchandise_iconb.addeventlistener(mouseevent.mouse_over, eye1); viewmerchandise_iconb.addeventlistener(mouseevent.mouse_out, standstill); 

i have error 'typeerror: error #1009: cannot access property or method of null object reference. @ tes_fla::maintimeline/standstill()'

every time try click viewmerchandise_iconb button. did wrong?

i'll send fla file if needed see error.

the application complaining "androideye2.gotoandstop(1);" says androideye2 (that specific instance or static class (depending on is)) not have property/function called "gotoandstop". androideye2 null/undefined when function (standstill) called.

edit1:

standstill(e){      trace("instance=" + androideye2);      trace("function=" + androideye2.gotoandstop);      androideye2.gotoandstop(1);  }
