Sometimes in loop code you need to initialize the entire array first, but I didn’t mention this since it was working for me. Also, you didn't say what the error message was.
function IIR2( input, f0, f1, f2 )
{
Result = 0;
result[ 0 ] = input[ 0
];
result[ 1 ] = input[ 1 ];//<---- getting error
etc…
