[wix-users] Can anyone give me a nice simple example of returning values from a Custom Action?

Hi, been banging my head against the wall on this!
I have a c# custom action to select an option and enter some text, how can
I reference and act on it in the wxs. Really id like to optionally install
different components depending on the select but I can seem to reference
the property returned in session.
Here is a sample:
<Property Id="THING_INSTALL_TYPE" Value="Default" />
DllEntry="SelectClientServer" Execute="immediate" Return="check" />
Will happily run the custom DLL.
In c# I say:
session["THING_INSTALL_TYPE"] = "Client";
Then in the WXS I want to conditionally install components based on the
result, see condition in bold below. I have to do it this way because of
various reasons but it just doesn't seem to return the property back from
the custom action. Any ideas?
<Component Id='AppComponentID' Guid='xxxxxxxx-3C67-4826-BB16-
<File Id='THINGEXEFileID' Name='THING.exe' DiskId='1'
Directory="ProgramMenuDir" Name="THINGWorkingDirectory='INSTALLDIR' Icon="
THING.exe" IconIndex="0" Advertise="yes" />
<Shortcut Id="desktopTHING" Directory="DesktopFolder" Name="
THING" WorkingDirectory='INSTALLDIR' Icon="THINGApp.exe" IconIndex="0"
* <Condition>**THING_INSTALL_TYPE = "Client"</Condition>*
