Problem with Split mode in grid.

I am using dhtmlxGrid v.3.0, im using split mode which allows to have grid separated into two parts with independent horizontal scrolling.i have included the js file but split mode is not working.
can anyone send me the splitmode js file.

im getting error msg as object doesn’t support this property or method. and the grid is not working.
please suggest me.
Thank you.

Split functionality is available only in PRO version of dhtmlxGrid.
