Open Subfolders with ?("folder")

I'm loving WexLite to the max.  Like everyone else I'd like to get a dynmic root of sorts working.  Not necessarily so however, i'd really like to just link things to the specific folder that i want.  This part i have working.  I made my wexroot variable look like so:

wexRoot = "c:\inetpub\wwwroot\" & request("folder")

Now if i do a link to default.asp?folder=sample

It will take me to that folder.  However, when i click on a subfolder of the folder i just requested, it doesn't display anything and the status box says "error opening folder !"

I'm assuming i need to change something about the openfolder command, however i'm very basic on the programming aspect (it took me 2 days to figure out the request("folder") thing so any code snipets would be awesome

I have the same problem...
