setColTypes + combo = error

We purchased the xGrid and xCombo so that I can have a standard combo in the grid… but when I use this line: grdItemSides.setColTypes(“combo,ro”) I get a message box: “Error type” configuration Description Incorrect celltype: combo"

I read the following article, and did what it said but… that’s how I got the issue. I am simply attempting to use the combox in your grid. What am I missing? … htmlxcombo



Please, check that dhtmlxGrid/codebase/excells/dhtmlxgrid_excell_combo.js is included.
