<script language=javascript>
function Data(t){

alert(doument.forms[0].combo_id.value);
document.forms[0].submit();
}
</script>

You need to assign the name of the combo box to a JS variable too, something like this:

<script type="text/javascript">
    var combo_name='<?php echo($Combo_name) ?>';

function Data(t){
    doument.forms[0].elements[combo_name].value = document.forms[0].t.value;
    alert(doument.forms[0].elements[combo_name].value);
    document.forms[0].submit();
}
</script>

Also, when posting code, it is a wise idea to use

, [code] and [code=html] tags, as they preserve the whitespace inside the code, making it easier to read.

If you want to access an HTML element with JavaScript, the parameter "id" should be defined. The parameter "name" should only be used to identify a field upon an HTTP request...
