I have two listboxes
listbox1. contains all the names of the treatments
listbox2 contains all the drugs name.
now the doctor has to check the listbox1 and listbox 2
to do billing.
All the drugs are quantity 1. i have given option by inputbox if he wants to increase the quantity then double click near the appropriate drug and add quantity for the drugs.
So far no probs now i should do billing can anybody tell me how to do billing in a very simple way.
