If this is a legacy dropdown form field, you need to check the formfield property 'Calculate on Exit' in order to force the update of the REF field. It should go without saying that Dropdown is the bookmark name of the dropdown form field. The usual default is Dropdown1 thus

{IF {Dropdown1} = "FIRST" "FIRST TEXT TO SHOW HERE" ""}{IF {Dropdown1} = "SECOND" "SECOND TEXT TO SHOW HERE" ""}{IF {Dropdown1} = "THIRD" "THIRD TEXT TO SHOW HERE" ""}

and of course you have to tab out of the form field for it to work and thus there needs to be another formfield to tab to.
