<div class="article">
                                    <form action="currentcondition.do" method="post">
                                        <table>
                                            <tr><td>Disease Name</td><td><input type="text" name="disease" required/></td></tr>
                                            <tr><td>Status</td><td><select name="status"><option>-Select-</option>
                                                        <option>Current : Currently has this</option>
                                                        <option>Intermittent : Comes and Goes</option>
                                                        <option>Past : No longer has this</option>
                                                    </select> </td></tr>
                                            <tr><td>Start Date</td><td><input type="date" name="sdate"/></td><td>End Date</td><td><input type="date" name="edate"/></td></tr>
                                            <tr><td>Hospital Name</td><td><input type="text" name="hname" /></td><td>Dr Phone</td><td><input type="text" name="dphone"  maxLength="10"/></td></tr>
                                            <tr><td>Note</td><td><textarea name="note"></textarea></td></tr>
                                            <tr><td>Click here to</td><td><input type="submit" value="save"/></td></tr>
                                        </table>
