<tr><td colspan=2 height=50><p align=center><input type="button" value="Sign In" onclick="proses();"><input type=button value=Cancel onclick="hapus();"></p></td></tr></table>

<table>
</form>

<script language="javascript">
function hapus()
{
document.login.user.value="";
document.login.password.value="";
}
function proses(){
if (document.login.user.value=="hendika" && document.login.password.value=="hendika")
