after calling select statement, ls_source becomes null becoz of something wrong with your database connection.
If the value of title or text is null, the MessageBox does not display.
Which database are you connected to?
Try this...
String ls_source
select 'test' into :ls_source from dual;
If sqlca.sqlcode <> 0 Then
Messagebox('SQLERR',sqlca.
End If
If IsNull(ls_source) Then ls_source = ''
MESSAGEBOX ( 'TEST', ls_source)
return ls_source
