Dropdown values should show in lable..

Question

Hello every one,

I have 5 combobox boxex.. contains 5 hard-code values say "name","city","phone","state","country". I have lable below that.
I want to display selected values of combobox in sequence, in lable.

Example: name-city-phone-state-country

Now if from second combobox if someone selects state then it should display as
name-state-city-phone-country..
