Thanks for the help Mark... when I do this, it says elements.optionName is not null or

function getValue(form, optionName,hiddenValue) {
s = form.elements[optionName];
for(i = 0;i < s.options.length;i++) {
if(s.options[i].value == hiddenValue) {
s.options[i].selected = true;
break;
}
}
}
onsomeformevent="getValue(this.form,'foo','bar')"
Cheers Mark
