Hi Pasan,
It should be fine if $tu would translate to NULL. The script handles
this case. But I'm afraid you have something else there, like another
deeper error that prevents the $tu variable to be evaluated.
Do you see any other errors before the mentioned ones ? what is the type
of route where you do the test ?

Hi Guys,
I have a check for NULL for $tu var in the script, But when the value
is missing I'm getting the following error.
ERROR:core:comp_scriptvar: cannot get left var value
WARNING:core:do_action: error in expression at
/etc/opensips/opensips.cfg:806
and line 806 contains following.
if ( $tu != NULL ) {
remove("location","$tu");
}
any suggestion on how to test for NULL values without getting above
error. I'm using opensips 2.3.5
