SetAccount option in .conf files

I am trying to get Asterisk to add the meetme conf number to the Account Code field of the DB, but I can’t figure out the correct syntax. I would also like to add the pin code to the Userfield if possible but I haven’t even attempted that yet. My last and best guess at the syntax is on Line 2:

exten => 12345,1,Set(MEETME_ROOMNUM=12345)
exten => 12345,n,Set(SetAccount=12345)
exten => 12345,n,GotoIf($["${DIALSTATUS}" = “ANSWER”]?READPIN)
exten => 12345,n,Answer
exten => 12345,n,Wait(1)
exten => 12345,n,Set(PINCOUNT=0)
exten => 12345,n(READPIN),Read(PIN,enter-conf-pin-number,)
exten => 12345,n,GotoIf($[x${PIN} = x139]?USER)
exten => 12345,n,GotoIf($[x${PIN} = x931]?ADMIN)
exten => 12345,n,Set(PINCOUNT=$[${PINCOUNT}+1])
exten => 12345,n,GotoIf($[${PINCOUNT}>3]?h)
exten => 12345,n,Playback(conf-invalidpin)
exten => 12345,n,Goto(READPIN)
exten => 12345,n(ADMIN),Set(MEETME_OPTS=aAwciMs)
exten => 12345,n,Goto(STARTMEETME,1)
exten => 12345,n(USER),Set(MEETME_OPTS=wciMs)
exten => 12345,n,Goto(STARTMEETME,1)
