Warning: 0 is not mSQL index

[Anon]

If I modify my php script I aleways get the following error:

Warning: 0 is not a mSQL query index in /usr/www/research/statistics/schools3.php3 on line 10

Does anyone have any idea what this means and how to fix it??? It always happen with the following statement:
$num2 = msql_numrows($district);

Here is a example of how I use the above statement.

  $result = msql("schools", "select * from teacounty where county clike '$county'");
  $num = msql_numrows($result);
  $i=0;
$code = msql_result($result,$i,"number");
$district = msql("schools", "select * from districts2 where DIST_NUMB like '$code%'");
$num2 = msql_numrows($district);
$j=0;

$code seems to be the problem. When you first intialize it the value it holds is of a link identifier. Also in the line ....

$code = msql_result($result,$i,"number");

..... is "number" the name of a field because it has to be. Examine what I mention and it WILL be apparent to you. Happy Coding ;-)
