function steps($cur) {
$dir=opendir("includes");
$maxnum=0;
$prev=$cur-1;
$next=$cur+1;
print "<table cellpadding=0 cellspacing=0 width=50%><tr>";
if ($cur > 1) {
print "<td>";
print "<a href=index.php?action=6&file=step".$prev.".html>";
print "<img src=/images/prev.gif border=0></a> ";

}
while($file = readdir($dir)) {
if (ereg("^step([0-9])\.html$",$file,$num)) {
if ($num[1] > $maxnum) {
$maxnum = $num[1];
}
}
}
for($i=1; $i<=$maxnum; $i++) {
if ($cur==$i) {
print "<td>";
