[chiPHPug-discuss] script question

[Roderick T. <tho...@ms...>]

$query=3D"SELECT CityID FROM Cities WHERE CityName =3D 'Ann Arbor, MI'";=


print "hello";
print "$city_selection";
print "hello";

$result=3Dmysql_query($query);
$num=3Dmysql_numrows($result);
$i=3D0;

while ($i < $num)
{
global $CityID;
$CityID=3Dmysql_result($result,$i, "CityID");
$i++;
print "$CityID";
}

The above script gives me this output:
helloAnn Arbor, MIhello1

Yet, the CityID doesn't show up when I use this query:
$query=3D"SELECT CityID FROM Cities WHERE CityName =3D '$city_selection'=
";
