[OpenSIPS-Users] How to prevent error when using invalid index on s.select

[Bogdan-Andrei Iancu]

Hi Brett,

the following script :
    $var(s)="1,2,3,4";
    $var(i)= 4;
    xlog("----------$(var(s){s.select,$var(i),,})\n");
    xlog("----------\n");
    $var(x) = $(var(s){s.select,$var(i),,});

does not produce the error you mentioned...

maybe you have something different ?

Regards,
Bogdan
