Radio button not being checked in Chrome and Firefox... works in IE

[timbofox]

The following code works fine in IE 678and9 and checks the relevant radio button but not in chrome or Firefox. Can anyone spot anything obvious?

document.write(' <input type="radio" name="useopt' + subid + '" value=1 ' + (eval('document.forms.mspage.text' + subid + '.useoptrb == "1" ? "checked" : "" ')) + ' onclick="useoptClick();" style="background-color:#0096ff;"> Default');
