Thanks Megatron but this wasn't what I need.
I have a text file with FirstNames and LastNames:

"names.txt"
Tom, Johns
Joe, Jordan
Ted, Brown
...etc.

I want to read in FirstNames (first column) into a ComboBox, and somehow reference to them LastNames (second column). So when user selects a first name from ComboBox, the corresponding Last name will show on a Label beside it.

example (see names above):
user clicks on Joe in the ComboBox, and Jordan appears in on the Label.

Thanx again
