jQuery Grid Plugin - jqGrid

Hi,

I am new to jquery, I am able to so far make the sample 'Your First Grid' to work, now I am trying to make the grid editable. I thought that the only thing I need to change is call 'editurl' instead of calling 'url' and make all the columns editable, that's all. But after I made the change on the call to editurl all the data of grid is now gone. Are there other things I should do? Is there a complete code html/php that I can look through to check what I miss?

Thanks.
