VFP 6.0

I have a list box (lstCustomers) and in the Interactive Change Event method I have placed the following code

Thisform.ResetLables()
Thisform.ResetPolicies()
Thisform.Refresh()

There is a second list box (lstPolicies) which is supposed to get refreshed by the second line of the code. It has

Rowsource = Thisform.aPolicies
RowSourceType = Array

I've checked to ensure that when Thisform.ResetPolicies() finishes executing the array Thisform.aPolices has the expected information. It can contain several rows and the problem is that only the first row is displayed in the list box.

Any ideas???

Thanks to all...............Rich
