Parameterised Build + SVN Polling : Unable to pick the parameter's value.

[ilikeflex]

Hi
 
I have scenario in which i have branch and i have multiple folders in it
 
Example:
 
http://servername/svn/finance/app/branches/refactor_part1
 http://servername/svn/finance/app/branches/refactor_part2
 http://servername/svn/finance/app/branches/refactor_part3
 http://servername/svn/finance/app/branches/refactor_part4
 
So i can make build from any folder in branch.
 
To solve this i have created parameterized build where 
SVN_LOCATION can be any one of the above location
 
and i am using Subversion, so i set 
REPOSITORY URL = $SVN_LOCATION
 
This is way parameterized parameters are passed.
So this is working great when build is created.
 
But at the same time, i am using svn polling. I am getting the below 
exception
So how can i pass the value to  $SVN_LOCATION so that i do not get the 
exception.
