combo box refresh

[jjjake01]

I have a form that views one record at a time.

The text boxes are data-bound to a dataset. The combo box value is also
databound to a dataset...but the combo box does not change when I move to
another record.
example:
onClipEvent(load) {
this.labelField = "PHONE";
this.text = _root.cust_ds.currentItem.phone;
this.refreshFromSources();
}

it will show the first record's phone number, but won't change when I move to
the next dataset, even with the refreshFromSources() code. It works with the
text field
