[javascript] JavaScript onclick redirect

Doing this fixed my issue

<script type="text/javascript">
    function SubmitFrm(){
        var Searchtxt = document.getElementById("txtSearch").value;
        window.location = "http://www.mysite.com/search/?Query=" + Searchtxt;
    }
</script>

I changed .value(); to .value; taking out the ()

I did not change anything in my text field or submit button

<input name="txtSearch" type="text" id="txtSearch" class="field" />            
<input type="submit" name="btnSearch" value="" id="btnSearch" class="btn" onclick="javascript:SubmitFrm()" />

Works like a charm.
