I am creating a grid to display the contents of a cursor. Only the first 5 columns of the grid have a proper caption and are bound to the cursor. If I look at the grid in the debugger, all the captions and controlsource are set correctly, but the grid does not display either the captions or data after the 5th column. Can anyone see the flaw in my technique?

THIS.RECORDSOURCE = "cCovering"
this.addobject('cName','column') 
this.cName.controlsource = "cCovering.name"
this.cName.header1.caption= "Name"
this.cName.width = 120

this.addobject('cOrd','column') 
this.cName.controlsource = "cCovering.ord"
this.cOrd.header1.caption= "Order"
this.cOrd.width = 40
 
* add on and configure all day columns
FOR nColumn = 3 to (lnDays + 2)
	cColumn = alltrim(str(nColumn - 2))
	this.addobject('cDay'+cColumn,'column')
	this.columns(nColumn).header1.caption = cColumn
	this.columns(nColumn).width = 70
	this.columns(nColumn).controlsource = 'cCovering.Day'+cColumn
ENDFOR

THIS.refresh  && refresh the grid
