Inline fields validation

[chrismcd]

Hello,
I am working on an order form, where if a customer enters any of three fields(checbox, size drop-down list, and a quantity textarea), an inline message (hidden textarea) appears. Then, when all the conditions are met, the message disappears. I was able to do this rather easily with FormCalc in another application, but am having real trouble figuring it out for Javascript. Any help would be greatly appreciated. Thanks.

Use a div and show using style.visibilit y = "visible". Validate on key press or onchange. Once the fields validate, hide the div by setting the style.visibilit y property to "hidden".
