phpQuestioner Posted February 5, 2008 Share Posted February 5, 2008 I guess IE has a problem changing the innerHTML of a select tag; never really ran into that before. Try This Instead: <script language="javascript"> function changeMenuOptions(what) { var months = document.getElementById("selectMonth").value; if (months == "3" || months == "5" || months == "8" || months == "10") { document.getElementById("selectDay").innerHTML="<SELECT name='day'><OPTION VALUE=\"1\" SELECTED>1</OPTION><OPTION VALUE=\"2\">2</OPTION><OPTION VALUE=\"3\">3</OPTION><OPTION VALUE=\"4\">4</OPTION><OPTION VALUE=\"5\">5</OPTION><OPTION VALUE=\"6\">6</OPTION><OPTION VALUE=\"7\">7</OPTION><OPTION VALUE=\"8\">8</OPTION><OPTION VALUE=\"9\">9</OPTION><OPTION VALUE=\"10\">10</OPTION><OPTION VALUE=\"11\" >11</OPTION><OPTION VALUE=\"12\">12</OPTION><OPTION VALUE=\"13\">13</OPTION><OPTION VALUE=\"14\">14</OPTION><OPTION VALUE=\"15\">15</OPTION><OPTION VALUE=\"16\">16</OPTION><OPTION VALUE=\"17\">17</OPTION><OPTION VALUE=\"18\">18</OPTION><OPTION VALUE=\"19\">19</OPTION><OPTION VALUE=\"20\">20</OPTION><OPTION VALUE=\"21\">21</OPTION><OPTION VALUE=\"22\">22</OPTION><OPTION VALUE=\"23\">23</OPTION><OPTION VALUE=\"24\">24</OPTION><OPTION VALUE=\"25\">25</OPTION><OPTION VALUE=\"26\">26</OPTION><OPTION VALUE=\"27\">27</OPTION><OPTION VALUE=\"28\">28</OPTION><OPTION VALUE=\"29\">29</OPTION><OPTION VALUE=\"30\">30</OPTION></SELECT>";
