Yeah this works. Thanks.
When i generate new address i use command like this "getnewaddress <account>"
So my request was look like "sendtoaddress <account> <address> <amount> <comment1> <comment2>"
Why this not work?

Im newbie in blockchain and stuck with this error.
So.
- I have a bitcoind on server with testnet and rpc params configured.
- I have a RPC client (on php) that send commands to server (bitcoind) - this part works well.
- I generate new btc addres (in test net): mperdjxACE12BsugcJQnv8PkBFV8KvYF23 and one more n1Ksts9eLrD13r3QTKmSyNoZbdjNgZMYhz.
- On each i send 1.1 btc from faucet sendbox (thanks them).
- get ballance command by rpc shows valid ballance 1.1 btc
- Try to `sendtoaddress` "mperdjxACE12BsugcJQnv8PkBFV8KvYF23 => n1Ksts9eLrD13r3QTKmSyNoZbdjNgZMYhz" command by rpc and get "Invalid Bitcoin address"
Whats can be wrong?
