I would do this with invisible DIV's which you can make visible or invisible in Javascript. I usually do something like obj.style.display = "" to show and obj.style.display = "none" to hide. if you want to get from the database every time you have to resubmit, which is slower and looks crap. > > //here is the if statement > if ($boo == '1') { > echo "<td width=\"350\" align=\"left\"><input > type=\"text\" > name=\"description\" onChange=\"javascript: > document.write(dsc)\"></td>"; } if you want $dsc to be available to the javascript you have to send it with the html, either as a hidden field or in the query string. In this case what you may be wanting to do is send the contects of $dsc in which case replace document.write(dsc) with document.write('" . $dsc . "')") or however you like to do this sort of concatenation. > > where $dsc is set equal to an array element read in from a database in > the php code.
