RPC Server 500 Error

[optimator]

I'm trying to send funds with the RPC.

Here's my JSON:

{"jsonrpc": "1.0", "id":"256a5750-3b89-414b-8d5e-e28d450ee88b", "method": "sendtoaddress", "params": ["19x68qBiQ1yLto9Ds1z6wPaP12Aa16JrER",0.50000000] }

However, bitcoind throws a 500 error when I attempt this. What am I doing wrong?

Code:

{"jsonrpc": "1.0", "id":"256a5750-3b89-414b-8d5e-e28d450ee88b", "method": "sendtoaddress", "params": ["19x68qBiQ1yLto9Ds1z6wPaP12Aa16JrER":0.50000000] }

it is a colon not a comma
