string and interger error?

[Anon]

what does this error mean?

Warning: Unable to jump to row 0 on MySQL result index 3 in c:\Program Files\Apache Group\Apache\htdocs\tastywet\artist_func.php on line 89

and

Warning: Can only count STRING and INTEGER values! in c:\Program Files\Apache Group\Apache/htdocs/tastywet/show_cart.php on line 42

from these lines of code?

if($cart&&array_count_values($cart))

and

$artist_price = mysql_result($result, 0, \"price\");

please help! thanks!

The first error means you are trying to fetch a result when there are no results. Always use mysql_num_rows() to make sure there are results before you start processing them.

The second error is probably due to you trying to process non-existant data.
