How to select a value from dropdown

Customer Name is the dropdown with almost 30 values, I want to select one value from the dr开发者_JAVA技巧op down in Watir script.

I have used the following code, but nothing is happening.

ie.select_list(:name, "Customers").select "Test"

Use 'set':

ie.select_list(:name, "Customers").set "Test"
