Java Snippet ComboBox Not Working

Hello - I am trying to create a simple java snippet for a combo box which the values for the drop down box are filled from a table creator node. The warning I get is that the variable Option cannot be resolved to be a variable. Any help would be appreciated. before you ask why it needs to be a combo box – we do not want user to have to select item w/in node each time this runs. Requirements are to have window where user can select item from drop down menu and proceed with flow.
