[Fatal Error]

Hello, I was wondering if you could help me with this. I keep receiving this error: [b]Fatal error: Cannot redeclare class template in /home3/ghostd0/public_html/includes/template.php on line 36[/b]

Here is my template.php coding ( starting from line #36 )
[code]class Template {
    var $classname = "Template";

    // variable that holds all the data we'll be substituting into
    // the compiled templates.
    // ...
    // This will end up being a multi-dimensional array like this:
    // $this->_tpldata[block.][iteration#][child.][iteration#][child2.][iteration#][variablename] == value
    // if it's a root-level variable, it'll be like this:
    // $this->vars[varname] == value  or  $this->_tpldata['.'][0][varname] == value
    // array "vars" is added for easier access to data
    var $_tpldata = array('.' => array(0 => array()));
    var $vars;[/code]

Can you please tell me what is going wrong? Thank you!!
