Thanks Balihr for your help! The problem solved. I've sucessfully installed the sql. It is very great module :)

There is only one problem I think.
I've filled in the url but no reaction when I clicked the banner.

I've removed the slide group and create again. But it still doesn't work.

Here is my website: http://www.laughmoreshop.com.

How to add the hyperlink on the banner images? Thanks again!
