Adding Dialog to Keep employee names

[PleaseHelp]

OK trying this on my own. How can you tell witch option out of 3 has been selected?

Example:
Option first
Option next
Option next

if (option first is selected)
out "Option 1 is selected"
if (option next is selected)
out "Option 2 is selected"
if (option next is selected)
out "Option 3 is selected"
