[Users] avp_db_load

Hello everyone, I'm trying to load an avp from the database, now from my understanding I simply use the avp_db_load() function. Now I previously setup my avp_table to be usr_preferences, now I'm doing the following: route[5] { xlog("L_INFO", "time [$Tf] method <$rm> r-uri <$ru> 2nd via <$hdr(via[1])>\n"); avp_db_load("$rU/username", "$avp(s:e911)"); xlog("L_INFO", "CURRENT AVP VALUE: $avp(s:e911)"); if(is_avp_set("$avp(s:e911)")) { xlog("L_INFO", "CURRENT \$ru: $ru"); avp_pushto("$ru", "$avp(s:e911)"); xlog("L_INFO", "AFTER \$ru: $ru"); } route(1); } For route 5, and I have a AVP row for 'e911' in the database, with the username, domain, and the attribute set, the attribute ofcourse being e911, type 0, and a value set. However, I keep getting NULL back for the AVP I'm trying to pull, does anyone care to explain what I'm doing wrong? Thanks. -- Brandon Armstead
