You are printing then before the assigment.

*xlog("L_INFO", "saldo:$dbr(ra=>[0,0]) y seg:$dbr(ra=>[0,1]) ");*

use

*xlog("L_INFO", "saldo:$var(credit) y seg:$var(cost_per_second) ");*

I just run a test with your values, and they did work.

$var(credit) = "0.0005";
$var(cost_per_second) = "0.0006";

*if (!cnxcc_set_max_credit("$var(client)",....*

Did not get that, what does not work?
