not getting proper display for dhtmlxcalender control

I see the demonstration of dhtmlx calender control on dhtmlx’s site…

it found descent on a site…



Then I used same dhtmlx calender control on my page…

While display it gave some issues like the main popup for calender control is fully transparent… and another popup display below main calender popup…



Please give me the proper solution to resolve these issues …



So that I can get a calender control like your sample pages …

like the main popup for calender control is fully transparent…
Image directory missed or incorrect path to image directory specified

Please be sure that next line specified on page, and points to correct location
