Try to do it in code after having the array filled in. E.g. this.rowsource = "thisform.myArray"

I meant this.requery(), e.g. requery a combo.

>Array is two dimensional

Wrong choice of words from my part again, sorry. I meant, could you use two columns and not 3 in your array just for test? In other words, having numerical value as the source for combo may be a bit of a problem (it should not).

Also try this.boundto = .t.

I think the problem is with setting combo's rowsource in design time. Try it in run-time and see, if it helps.
