[Serusers] avp_db_store

I have almost all of the other parts of AVP functioning great but I can't seem to get avp_db_store to work from CVSHEAD. Below is an example and the debug. Not sure if it's my syntax or bug Thanks for an help if(uri=~"sip:\*78@.*") { log(1, "LOG: Enable DND\n"); avp_write("$to/username", "$to_id"); avp_write("$from/username", "s:fromuser"); avp_db_load("$from/username", "s:7879"); avp_print(); avp_db_store("$from/username","i:7879"); rewritehostport ("xxx.yyy.83.5:5060"); route(9); break; }; 8(22938) DEBUG:avpops:load_avps: loaded avps = 1 8(22938) DEBUG:avpops:print_avp: p=0xb61a8340, flags=B 8(22938) DEBUG: name=<7879> 8(22938) DEBUG: val_str=<> 8(22938) DEBUG:avpops:print_avp: p=0xb61a82e4, flags=3 8(22938) DEBUG: name=<fromuser> 8(22938) DEBUG: val_str=<4107358551> 8(22938) DEBUG:avpops:print_avp: p=0xb61a82a0, flags=2 8(22938) DEBUG: id=<57920> 8(22938) DEBUG: val_str=<*78> 8(22938) DEBUG:avpops:store_avps: 0 avps were stored
