javascript - Flexslider only Horizontal Slide not work -

i ask problem find error.. error appears :

<script type="text/javascript"> (function($){  $(document).ready(function(){    $('#banner-slider-text').flexslider({     animation: "slide",     direction: 'horizontal',   });  }); })(jquery); 

exactly on "slide" "horizontal" appears problem dont slide ... when in code view chrome or firebug see "activ" slide changed not visual. dont slide anyways. slide + vertical work, fade + vertical work, fade + horizontal work, slide + horizontal not work.

flexslider vers 2.* jquery ver 1.9 - 2.* testet  shopware vers 4.3.6 

slider coded in smarty tpl slider options , loaded in home index tpl mainpage.

after alot of debugging found out @ code line 928 style set , here width slider.computedw variable nan ... thats reason why dont set ... , @ code line 874 target transform translate3d nan ... no transform element animation

928 settimeout(function(){         slider.domath();         slider.newslides.css({"width": slider.computedw, "float": "left", "display": "block"});         // smooth height:         if (slider.vars.smoothheight) { methods.smoothheight(); }       }, (type === "init") ? 100 : 0);  874 if (slider.transitions) {     target = (vertical) ? "translate3d(0," + target + ",0)" : "translate3d(" + target + ",0,0)";     dur = (dur !== undefined) ? (dur/1000) + "s" : "0s";     slider.container.css("-" + slider.pfx + "-transition-duration", dur);      slider.container.css("transition-duration", dur);   } 

maybe thats reason why slide horizontal dont work .... not sure
