That's very helpful.
I thought to place a Description field into a template which can then be modified later.
The result of this is
<meta name="description" content=" <?php echo($Rs->getColumnVal("metadescription")); ?>">
showed at the top of the page although it is placed in the <head> area.
I did not update the template to the pages, I opened F12 the template.
Also showed when using Live Code button
