 * Make any input elements look like the one below, adding the new parameters
 * pattern - uses regular expressions to match text against a pattern
 * errorMsg - message displayed to user whan an invalid statement is entered
 * example
 * First Name: <input type="text" name="fname" maxsize="20" size="20"
 *       pattern="[^A-Za-z]+" errorMsg="Invalid character found in first name"
 *       onfocus="changeColor(this);"  found in FmoCommonScripts.js/>
