and call this inside the checkbox input tag - with an onchange event.

You might wanna add checker so that the function is only triggered when the checkbox is actually checked.
e.g.

function populateTextBoxes() {
	if (document.forms.form1.checkbox.checked == true) {
	document.form1.mytextbox.value = document.form1.combobox.value;
	}
}

It's also an idea to add in some else code that clears the second set of input fields if the checkbox is then unchecked.
