[OpenSIPS-Users] problem with pv string concatonation

[Brett Nemeroff]

Hey All,
Weird problem here. This does not work:
$rU =  $avp(s:lnp_prefix) + $rU;

When I do that, $rU appears "unchanged"

But if I do:
$rU = '' + $avp(s:lnp_prefix) + $rU;

It works fine!

Am I doing something wrong here?

Thanks,
Brett
