function setFocus(formName,fieldName){

if (document.forms[formName] &&
document.forms[formName].elements[elementName] &&
document.forms[formName].elements[elementName].focus)
{
document.forms[formName].elements[elementName].focus()
}
else{
alert('Either the field or the form doesn't exist')
}
}
field.focus()

Only if field is a fully qualified reference to the field. Otherwise it
is an IE only solution.

Can the dot notation used in this example be replaced with
getElementById ?

Only if the if of the element is known.

function setFocus(fieldID){
var elm = document.getElementById(fieldID);
if (elm && typeof elm.focus == "function")
elm.focus();
}

Only if the *ID* of the element is known.

^^^^^^^^^^^

elementName should be fieldName

Great, I was concerned because I'm updating some of my pages with that.

Thanks Daniel and Randy for the replies and info.
