We have this homework..
The LRT Train Ticketing System
For each three stations I may ride on , I get to pay P15.. +5 if i exceeded more than three stations..
e.g Station1-Station5 costs P20...Station1-Station8 costs 25...
how can I display the Fee in a textbox if I put a ComboBox1 for my origin and ComboBox2 for the destination??
