Looks to be IE only. Note the need to reference the form.

with(document.forms[0]){
for (var optionCounter = 0; optionCounter < frmCountry.length;
optionCounter++) {
frmCountry.options[optionCounter].selected=
(frmCountry.options[optionCounter].value==hidCountry.value);
}
}

This is OK, but the forms collection works on more browsers.

var frmCountry = document.forms["formName"].elements["country"];

//If this loop is within a function, I would use:
var o=frmCountry.length
while(o--){with(frmCountry.options[o]){
selected=(value==hidCountry.value);
}
}
