Script trigger to make sure user  enters data


     I have a field on a layout.  I want to set a script trigger that evaluates if data is in a field and if so, will not allow a user to clear the field.  Rather, a user can change the value or leave the current value.  If the field was blank to begin with, nothing will trigger.  If the field is blank and a user enters data and clears it, nothing should trigger.  For the last example I think I may have to use a popup layout where records can't commit until  the window is closed and a script runs (using the web viewer trick (web viewer blocks a user from clicking outside a field to commit the record)). 

     Is this possible?
