Filtering SQL with 2 variables

Im trying to filter my db with 2 variables in the sql im using "project_category" to filter what category it is and "fieldset_Category_Category" to filter it down further. the code i have came out as follows

$colname_Recordset1 = "-1";
if (isset($_GET['project_category'])) {
$colname_Recordset1 = $_GET['project_category'];
}
$year_Recordset1 = "-1";
if (isset($_GET['fieldset_Category_Category'])) {
$year_Recordset1 = $_GET['fieldset_Category_Category'];
}

$query_Recordset1 = sprintf("SELECT * FROM project WHERE project_category LIKE %s AND fieldset_Category_Category <> %s ORDER BY id ASC", GetSQLValueString("%" . $colname_Recordset1 . "%", "text"),GetSQLValueString($year_Recordset1, "int"));

when i run the code i get all tables when it should limited not sure if im going about it right or not. Im also sending the variables like this "?project_category=Leaseback&amp;year=2011-2125". I know the first part works perfectly but the second variable is messing it up and not narrowing it down.

thanks in advance

the colname variable looks right, but the year variable is wrong.

the year variable has the run time value set to:
$_GET['fieldset_Category_Category']


but your link is passing the year as a variable named year, not named fieldset_Category_Category. the run time value should be:
$_GET['year']

also, the data type for the year variable is set to Integer. the value you are passing is not an integer:
2011-2125

an integer cannot contain any characters that are not numbers, like the dash.

i solved it

$colname_Recordset1 = "-1";
if (isset($_GET['fieldset_Category_Category'])) {
$colname_Recordset1 = $_GET['fieldset_Category_Category'];
}
$colname2_Recordset1 = "-1";
if (isset($_GET['project_category'])) {
$colname2_Recordset1 = $_GET['project_category'];
}
mysql_select_db($database_acme, $acme);
$query_Recordset1 = sprintf("SELECT * FROM project WHERE fieldset_Category_Category LIKE %s AND project_category LIKE %s ORDER BY id ASC", GetSQLValueString("%" . $colname_Recordset1 . "%", "text"),GetSQLValueString("%" . $colname2_Recordset1 . "%", "text"));


in short i had to use LIKE 2 times to get both fields to show up with the AND in the string im telling it there is more than 1 filter


thanks for your help Jason you pointed me in the right direction
