Super

[ceyesuma]

My question is concerning Super.
If someone is farmiliar with Super . Is it possible to get someone to look at the first and of code only and get me started on how I would approach the concept of using Super. Because the second two blocks of code are almost identical. and I plan on creating two more blocks of code to create almost the same senerio.
(a combobox calling a child.)
Thanks
