HI, by text wrapping, you're referring to the question labels, correct? If you want them to wrap, please reset your colspan back to 1 for the textboxes. And the width of 400, is this for the question label also or the textbox field? Also, please check out our Form Demos, especially Form Demo 19 here.
By setting the colspan back to 1, the question label text should wrap if it's more than 400 characters long (if you've set your question width to 400).
