I tried to use pvar holding len but got an error.

Jul 11 14:51:37 localhost /usr/sbin/kamailio[16905]: ERROR: pv
[pv_trans.c:434]: select cannot get p1
Jul 11 14:51:37 localhost /usr/sbin/kamailio[16905]: ERROR: <core>
[lvalue.c:351]: non existing right pvar

This is part of my config file:
        $avp(varname) = '1';            <---- pseudo variable holding a
positive integer
        $avp(result) = $(fU{s.strip,$avp(varname)});            <----
s.strip

How can i  use variables with transformation ?
