I can't account for why the wizard assigns php virtual to your page, perhaps its a new thing - maybe Jason can help with that.
However, you can try the following, replacing the lines as follows...
<?php virtual("/webassist/form_validations/wavt_scripts_php.php"); ?>
<?php virtual("/webassist/form_validations/wavt_validatedform_php.php"); ?>
with
<?php require_once("../webassist/form_validations/wavt_scripts_php.php"); ?>
<?php require_once("../webassist/form_validations/wavt_validatedform_php.php"); ?>
(note you may need to change the path slightly in your particular instance)
