Unselectable, Unclickable, Unavailable Text Boxes HTML

You have your text box and you cannot click into the text box to type any text. No curser, no typing, nothing it's like it's not there at all. Have you been using z-index in your CSS? It seems if the text box is in a lower z-index the page can't access the box as theoretically it's hidden. You'll have to rething your z-indexing.
