function updateCC(rowNum) {
document.prices("cc" + rowNum).value = document.prices("cost" +
rowNum).value * 1.2;
}
But it's widely considered better practice to use document.getElementById()
rather than document.formname to reference form fields. To do so, just ad
id="" to the fields, and the function would become:
function updateCC(rowNum) {
document.getElementById("cc" + rowNum).value =
document.getElementById("cost" + rowNum).value * 1.2;
}
