diasable text area in javascript

[niraj.kumar.ait]

I want to disable my text area based on its id .When I concatenate my
id back to form its gives me an error that NAME is not an fh1 object
..Its taking it as a constant .Any suggestion..

function putvalue(myid)
{
var fh1 = document.myForm;

var id = myid;

if(id)
{
var NAME = 'MSG_' + id ;
fh1.NAME.disabled = true;
}

TIA
Niraj
