Fill list box based on data selected in another list box
I have 4 list boxes
The first list box contains a set of values and based on the list of values selected by the user, the values appear in the second list box
Now based on the values that are in the second list box, i need to find the matching records from a data master to populate the third list box.
I am not able to fill the list box from the data master based on the values in the second list box
