If you would use asp dropdownlist you could select it easier by testSelect Text   Now you d have to do a Request Form  testSelect   to get the value after pressed btnTes   Hope it helps   EDIT  You need to specify a name of the select  not only ID  to be able to Request Form  testSelect

You need to add a name to your  lt select gt  element    lt select id  testSelect  name  testSelect  gt    It will be posted to the server  and you can see it using   Request Form  testSelect
