You n eed to know that in almot all cases that the tpl file describes the display of information gathered from other files. You now have the page display ok but there is no data to draw from to populate this.
You can inline code this data if it does not change or create another file to gather this info from the DB and make it dynamic if and when the data might be changed.
You have to look at the code I referenced earlier for exactness but a general area would be tpl_contact_us_default.php and includes/modules/pages/contact_us/header_php.php
Basic code for this would be the following but you need to apply a table where this info exists and the zen type of code that you find in the referenced files. also apply a name to the retreived data to be used in your tpl file
Code:
mysql_connect("localhost","root","password") or die (mysql_error()); // "root" is the default username.
mysql_select_db("database") or die (mysql_error());
$column = ""; // Set which column to be retrieved.
$table = ""; // Set which table to retrieve column from.
$query="SELECT $column FROM $table";
$result = mysql_query($query);
// echo the select tag:
echo "<select name=\"bla\">";
// Lets loop through the result:
while($row = mysql_fetch_array($result)) {
echo "<option value=\"$row\">$row</option><br/>\r\n";
}
// echo the closure of the select tag:
echo "</select>";
