problem displaying from mysql

hai, i'm trying to get the grid working with php/mysql, but when i select a db, table and some fields.. it wont show anything..
i double checked my sql info is right..

this is the source in html when i open basic.php

<html>
<head>
    <title>ActiveWidgets Grid :: PHP Example</title>
    <style> body, html {margin:0px; padding: 0px; overflow: hidden;font: menu;border: none;} </style>

    <!-- ActiveWidgets stylesheet and scripts -->
    <link href="../../runtime/styles/xp/grid.css" rel="stylesheet" type="text/css" ></link>
    <script src="../../runtime/lib/grid.js"></script>

    <!-- ActiveWidgets PHP functions -->
        
</head>
<body>

<script>
var _columns = [

];
var _data = [
];
try {
  var  = new Active.Controls.Grid;
  .setRowCount();
  .setColumnCount();
  .setDataText(function(i, j){return _data[i][j]});
  .setColumnText(function(i){return _columns[i]});
  document.write();
}
catch (error){
  document.write(error.description);
}
</script>

</body>
</html>

anyone knows how 2 solve this?

There isn't any data in this code. It can't display what isn't there. You are making an error in your PHP code, otherwise there would be information between your "var _data = [ " and your "];".
Post the PHP code and we might be able to assist you. But from what you have posted above, the grid is working properly.

ok, the main problem is solved.. i dont know what it was, but i uploaded it today and it works! great stuff!
It seems to be i cant select the fields that will be added to the grid, because every field is showing up now:S. this is my script:

<html>
<head>
    <title>ActiveWidgets Grid :: PHP Example</title>
    <style> body, html {margin:0px; padding: 0px; overflow: hidden;font: menu;border: none;} </style>

    <!-- ActiveWidgets stylesheet and scripts -->
    <link href="../../runtime/styles/xp/grid.css" rel="stylesheet" type="text/css" ></link>
    <script src="../../runtime/lib/grid.js"></script>

    <!-- ActiveWidgets PHP functions -->
    <?php include("activewidgets.php") ?>
    <?php include("config.php") ?>

</head>
<body>

<?php

    // grid object name
    $name = "obj";

    // SQL query
    $query = "select * from `leden`  limit 0,20";

    // database connection
    $connection = mysql_connect("$host", "$user", "$ww");
    mysql_select_db("$db");

    // query results
    $data = mysql_query($query, $connection);

    // add grid to the page
    echo activewidgets_grid($gebruikersnaam, $automerk, $type);

?>

</body>
</html>

how can i only select $gebruikersnaam, $automerk and $type?

you need to learn a little mysql.

Specifically in this case select * from... gives you all fields.

select a,b,c from... would give you only fields a,b and c

or he could do something like this:
$html .= " $name.setColumnValues([1,4,5,7,9,10,12]);\n";

to show only columns 1,4,5,7,9,10 & 12

oops forgot to say wher to put:
$html .= " $name.setColumnValues([9,10,11,12]);\n";

put it in the include("activewidgets.php") file
