the answer was i wasn't passing anything into the js as required, i will paste everything back in...

function EnableDisableButtons() should have been

function EnableDisableButtons(tablename, itemname)

 var grid = igtbl_getGridById(tablename);
                var row = igtbl_getRowById(itemname);
                var cell = row.getCell(15).getValue();

                if (cell != 'APPT') {
                    document.getElementById('ctl00_ContentPlaceHolder1_ddlResults').disabled = true;
                    document.getElementById('ctl00_ContentPlaceHolder1_btnSaveResult').disabled = true;
                    document.getElementById('ctl00_ContentPlaceHolder1_btnContact').disabled = true;
                    }
                else if (cell = 'APPT') {
                    document.getElementById('ctl00_ContentPlaceHolder1_ddlResults').disabled = false;
                    document.getElementById('ctl00_ContentPlaceHolder1_btnSaveResult').disabled = false;
                    document.getElementById('ctl00_ContentPlaceHolder1_btnContact').disabled = false;
                    }
             }

Hi,

I could see syntax errors in the script.

Try replacing var type = grid.Rows[grid.ActiveRow.Index].Cells[15].Text as follows:

var type = grid.Rows.getRow(grid.getActiveRow().Index).getCell(15).getValue();

I think this should remove script error.
