[mapguide-users] How to get selected area information in mapguide

[nekad]

Thank Kenneth for the reply..

I've figured out that it is caused when InitializeWebTier and the included
file location is wrong....

now, I can get the map and layer name to the screen,
but, the problem is $_POST['SELECTION'] seems not be set 
when i run isset($_POST['SELECTION'] it return false

I've already select an area in my map, but why the selection is false?
and 4 your information, i just have one layer, but it consist of separated
area
such as, I have layer name 'Indo', when it shows in web layout, there will
be a line that separated one area to another...

please, can you help me?
