Just an update and a thank you to whoever updated my wikipage to a much more manageable address.
http://www.jsoftware.com/jwiki/BobTherriault/Visualize The update is a third file that I have added as an attachment - vlitejwiki2.ijs - which will now handle " embedded in the text edit box. Thanks to Brian Schott for pointing the bug out and for his suggestions. I also made the display a little smaller. It is easy to adjust this by changing the CSS #text { ... font-size: 1.5em ... } to whichever size you prefer.
