Error message in functions.php no matter what child theme I upload

[Deluxe Designs]

I have uploaded Genesis and then a few different child themes. No matter what theme I use, I get the same error message (substituting child theme)

Warning: require_once(/home/cordell5/public_html/wp-content/themes/Crystal/custom-header.php) [function.require-once]: failed to open stream: No such file or directory in /home/cordell5/public_html/wp-content/themes/PrettyYoungThing/functions.php on line 4

Fatal error: require_once() [function.require]: Failed opening required '/home/cordell5/public_html/wp-content/themes/Crystal/lib/custom-header.php' (include_path='.:/usr/lib/php:/usr/local/lib/php') in /home/cordell5/public_html/wp-content/themes/PrettyYoungThing/functions.php on line 4

Any ideas? Genesis uploads and can activate just fine…

I have a maintenance mode plugin right now on the site but can give someone access if need be.
