Pear paging numrows() probelm

Hello!Can anyone help me with this problematic code!
I use mysql and php ,and the DB_Pager-0.7
It comes as the answer to a form.
It shows the correct results in the first page, and the following errors comes up when you want to see the res tof the resulting ages.
It warks perfectly if I use fixed values where the $_POST... variables are.
Fatal error: Call to undefined function: numrows() in Crogram FilesApache GroupApache2htdocsPager.php on line 94

<?php
function pc_print_link($inactive,$text,$offset='') {

if ($inactive) {
printf('<font color="#666666">%s</font>',$text);
} else {
printf('<a href="%s?offset=%d">%s</a>',$_SERVER['PHP_SELF'],$offset,$text);
}
}


function pc_indexed_links($numrows,$offset,$per_page) {
$separator = ' | ';

// print "<<Prev" link
pc_print_link($offset == 1, '<<Prev', $offset - $per_page);


// print all groupings except last one
for ($start = 1, $end = $per_page;
$end < $numrows;
$start += $per_page, $end += $per_page) {

pc_print_link($offset == $start, "$start$end", $start);

// print "Next>>" link
print $separator;
pc_print_link($offset == $start, 'Next>>',$offset + $per_page);

This is it !Thanks in advance

OK - quoting what you wrote the first time didn't help. Try putting your code in php tags and/or highlighting the row you are having problems on. Also is all that code really necessary.

My basic rule of thumb - If I can't figure out what you are trying to ask and where the problem is in under 20 seconds - I move on.
