Thank you. One question as I don't know much about javascript at all.
When go to Tools > Javascript > Document Javascript, the dialog box asks me to name the script, which I did--called it DateTime, and it gives me this text:
function DateTime ()
{
}
Exactly between which things do I paste the script you gave me?
I tried a couple of placements, but it kept telling me I needed a parenthesis before part of it.
