May be if you try RETURN (Cstr("")) instead of RETURN ("")

I found a same problem when i fill a array with "" (emty strings)
arr=["","","",""]   'all entries are 'Null'
must corected to 
arr=[Cstr(""),"","",""] all entries are now ""

Gambas sees a variable preset with "" as Null in relational compares as 

anemtystring=""
IF anemptystring = "" THEN 
 print "this is empty"
ELSE
 print "this is NULL"
ENDIF
