Infamous no input file specified error with a twist

[eluser]Unknown[/eluser]
I have read many posts about this error, and all seem to correct the problem quickly with an htaccess file tweak. I have tried this, but I have a situation where a page in the mfind (mobile find) directory is pointing to all of the code except for the views in another folder (../find) Find works just find, but mfind returns the input file not found error. The following are snippets from the index and htaccess in the mfind directory.

Thanks in advance.

/find
/application
...

/mfind
index.php
...
$system_path = '../find/system';
$application_folder = '../find/application';
$view_folder = 'views';
...
