unfortunetly, placing the xml data on the page does not seem to be working either.
I’ll post all my code for the scheduler:
<div id='scheduler_here' class="dhx_cal_container" style='width:1130px; height:900px;'>
    <div class="dhx_cal_navline">
        <div class="dhx_cal_prev_button"> </div>
        <div class="dhx_cal_next_button"> </div>
        <div class="dhx_cal_today_button"></div>
        <input type="button" id="save" value="save" onclick="save()">
        <div class="dhx_cal_date"></div>
        <div class="dhx_cal_tab" name="day_tab" style="right:204px;"></div>
        <div class="dhx_cal_tab" name="week_tab" style="right:140px;"></div>
        <div class="dhx_cal_tab" name="timeline_tab" style="right:280px;"></div>
        <div class="dhx_cal_tab" name="month_tab" style="right:76px;"></div>
    </div>
    <div class="dhx_cal_header">
    </div>
    <div class="dhx_cal_data">
    </div>
